## Bottom line

On these facts, Ironvale should **not** treat the strike as a pure economic strike. The June 3 elimination of the $1.75 evening-shift differential was a **material unilateral change to a mandatory subject of bargaining** made while bargaining was ongoing, with no agreement, no established past practice, and no genuine emergency. That violation materially contributed to the strike and to its continuation. Therefore, under Severn law, the strike is best characterized as a **mixed-motive strike with unfair-practice status**.

The practical consequence is significant: Ironvale’s June 10 designation of 60 replacements as “permanent” is not valid as a defense against reinstating nonmisconduct strikers. The union’s **June 25 unconditional written return offer** triggered the right of nonmisconduct strikers to **immediate reinstatement**, displacing replacements to the extent necessary. Back pay is therefore running from June 25 for each nonmisconduct striker whom Ironvale has not timely reinstated, subject to mitigation.

The three named individuals must be handled separately. The bottle-thrower and the recorded threat-maker may lawfully lose reinstatement rights if Ironvale makes an individualized, credible finding of serious misconduct. The worker who briefly blocked a truck entrance and moved when police instructed the group to clear does **not** automatically forfeit reinstatement rights and should be reinstated with the other nonmisconduct strikers.

Ironvale’s best strategy is not to defend the “economic strike” label. The contemporaneous evidence is strong against that label. Ironvale should immediately restore the differential, reinstate all nonmisconduct strikers, displace replacements as necessary, calculate and pay or settle back pay, individualize misconduct, and resume good-faith bargaining.

# 1. The June 3 schedule-pay change was an unlawful unilateral change

Under Severn Rule 5, an employer violates the duty to bargain by making a **material unilateral change** to a mandatory subject while bargaining is ongoing, absent:

1. agreement with the union;  
2. an established past practice permitting the change; or  
3. a genuine emergency.

All three elements point to liability here.

### A. The change concerned a mandatory subject

The eliminated $1.75 evening-shift differential is a wage or compensation item. It is clearly a mandatory subject of bargaining.

### B. Bargaining was ongoing

Ironvale and the union began bargaining on May 1. The union demanded a 6 percent wage increase; Ironvale offered 2 percent. On June 3, the facts state that bargaining continued. The existence of a May 28 strike authorization does not end the duty to bargain. A strike authorization, or even a strike, does not give an employer the right to impose a material unilateral change during ongoing bargaining.

### C. The change was unilateral

Ironvale eliminated the differential without union agreement. The company had **never previously changed the differential without bargaining**, so there was no established past practice. There was also no genuine emergency. The internal email makes clear that the change was not an administrative necessity or emergency response:

> “Cut it now. They need to understand that delay has a cost.”

That statement is adverse to Ironvale. It suggests that the company made the change as a bargaining pressure tactic, not because of an emergency or established practice.

### D. The change was material

A $1.75 evening-shift differential is likely material, particularly for employees who worked the evening shift. Even if the dollar amount were modest for some employees, materiality is not measured only by the size of the change. Timing, purpose, and effect on the labor dispute are also relevant. Here, the change occurred immediately before the strike notice, was expressly cited by the union, and was offered as a condition for ending the strike. That makes it difficult for Ironvale to argue the change was immaterial.

**Conclusion:** The June 3 elimination of the evening differential violated Ironvale’s duty to bargain.

# 2. The strike was mixed-motive but has unfair-practice status

## A. It was not a pure economic strike

Under Severn Rule 1, an economic strike is one whose objective is to obtain wages, hours, or other bargaining concessions. This strike had an economic objective: the union demanded a 6 percent wage increase, and Ironvale had offered 2 percent. Picket signs also referred to “6 percent.” So the strike was at least partly economic.

But the strike was not solely economic.

The June 5 strike notice said:

> “Employees will strike over Ironvale’s inadequate wage proposal and its unlawful unilateral elimination of the evening differential.”

The picket signs referred both to “6 percent” and “restore our shift pay.” The June 12 bargaining note shows the union offered to end the strike immediately if Ironvale restored the differential and resumed wage bargaining.

Those facts establish **mixed motives**: the employees were striking over both wage increases and the unlawful unilateral pay cut.

## B. Under Severn Rule 2, the violation’s material contribution controls

Severn Rule 2 provides that a strike may have mixed motives, but it is an unfair-practice strike when the employer’s unfair labor practice **materially contributed** to the decision to strike or to continuation of the strike, even if economic demands also existed.

Here, the June 3 unilateral change was made while bargaining continued. The next day, the union demanded restoration and called the change unlawful. The following day, the union issued a strike notice expressly citing the unlawful unilateral elimination of the differential. Picket signs continued to refer to restoring shift pay. On June 12, the union offered to end the strike immediately if the differential was restored and wage bargaining resumed. Ironvale refused.

That sequence strongly supports the conclusion that the unlawful change materially contributed to the strike and to its continuation.

Ironvale may argue that the wage dispute was the primary motive because employees had already authorized a strike on May 28, before the June 3 change. But Severn Rule 2 does not require the violation to be the sole or even the dominant cause. It only requires that the violation materially contributed to the decision to strike or to continuation. The June 5 notice, picket signs, and June 12 offer show that the differential was not a peripheral issue.

**Conclusion:** The strike was mixed-motive, but because the unlawful unilateral change materially contributed to it, it is an **unfair-practice strike** for purposes of replacement and reinstatement.

## C. Consequence of mixed motives

The consequence is that Ironvale cannot simply label the strike “economic” and retain permanent replacements. The economic wage demand does not immunize the strike if the employer’s unfair labor practice materially contributed.

A mixed-motive strike that materially involves an employer violation deprives the employer of the permanent-replacement defense that would otherwise be available in a pure economic strike.

---

# 3. Significance of the key documents

## A. June 5 strike notice

The June 5 notice is direct evidence that the strike had a dual purpose:

1. the wage proposal; and  
2. the unlawful unilateral elimination of the evening differential.

This undermines any argument that the strike was exclusively economic.

## B. Picket signs

Picket signs are strike communications. They show that workers were publicly demanding both:

- “6 percent,” i.e., the economic wage demand; and  
- “restore our shift pay,” i.e., the differential.

Together with the strike notice, they show mixed motives and reinforce the union’s claim that the differential was a real and material part of the dispute.

## C. June 12 bargaining offer

The June 12 note is particularly important. It states that the union offered to end the strike immediately if Ironvale:

1. restored the differential; and  
2. resumed wage bargaining.

That offer shows that the differential was not merely rhetorical. It was a discrete issue that, if fixed, could have ended the work stoppage. Ironvale’s refusal to restore the differential supports the conclusion that the employer’s violation prolonged the strike.

It also shows that Ironvale had a clear opportunity to de-escalate the dispute. It chose not to take it.

## D. Internal email

The internal email is damaging in several ways.

First, it confirms that the change was deliberate. Second, it suggests the purpose was to pressure the union: “They need to understand that delay has a cost.” Third, it undercuts any claim that the change was necessary due to an emergency. Fourth, it makes it harder for Ironvale to argue that the violation was immaterial or that the union’s reaction was disproportionate.

Under Severn Rule 8, contemporaneous notices, bargaining records, and strike communications are relevant. The internal email is part of the bargaining record and is highly relevant to the employer’s motive and the materiality of the violation.

# 4. Permanent-replacement rights under each classification

## A. If the strike were purely economic

Under Severn Rule 3, if the strike were purely economic:

- Ironvale could hire permanent replacements;
- economic strikers would remain employees; and
- they would be entitled to preferential recall as vacancies arose.

In that scenario, the June 25 unconditional return offer would not automatically require immediate reinstatement over permanent replacements. Ironvale would need to recall economic strikers only as vacancies arose.

But that is not the correct classification here.

## B. If the strike is unfair-practice

Under Severn Rule 4, if the strike is unfair-practice:

- replacements may be only temporary;
- strikers may not be permanently displaced; and
- upon an unconditional offer to return, they are entitled to immediate reinstatement, displacing replacements if necessary.

This is the applicable rule on these facts.

## C. If the strike is mixed-motive

A mixed-motive strike is treated as an unfair-practice strike if the employer’s violation materially contributed to the strike or its continuation. Here, it did.

Therefore, the mixed-motive nature of the strike does not allow Ironvale to keep permanent replacements. The material violation controls.

**Conclusion:** Ironvale may not rely on the permanent-replacement defense for the nonmisconduct strikers.

---

# 5. Effect of the June 25 unconditional return offer

The union’s June 25 unconditional written offer for every striker to return is the critical triggering event.

Under Severn Rule 4, once nonmisconduct unfair-practice strikers make an unconditional offer to return, they are entitled to immediate reinstatement. If their positions have been filled by replacements, the replacements must be displaced to the extent necessary.

Placing the strikers on a preferential-recall list is the remedy for economic strikers, not for nonmisconduct unfair-practice strikers. It is therefore legally inadequate here.

The fact that Ironvale reinstated only twelve people into vacancies and placed the rest on a recall list does not cure the violation. For every nonmisconduct striker who has not been timely reinstated, Ironvale has an ongoing reinstatement obligation.

The offer must be honored unconditionally. Ironvale cannot condition reinstatement on, for example:

- withdrawal of unfair labor practice charges;
- a waiver of back pay;
- acceptance of lower wages or benefits;
- resignation from the union;
- a new hire-or-rehire procedure that delays reinstatement; or
- any other condition that interferes with the right to return.

---

# 6. Reinstatement and back-pay exposure

## A. Who must be reinstated immediately

Ironvale must immediately reinstate all nonmisconduct strikers who are entitled to reinstatement under the unfair-practice classification.

That includes:

- the remaining strikers not tied to misconduct; and
- the third named individual who briefly blocked a truck entrance and moved when police instructed the group to clear.

The two individuals with serious misconduct may be excluded only through an individualized process.

## B. What “immediate reinstatement” requires

For each nonmisconduct striker, Ironvale should:

1. issue a written reinstatement notice;
2. restore the employee to the former position or a substantially equivalent position;
3. restore the prior wage rate, including the evening differential where applicable;
4. restore seniority and benefits to the extent required; and
5. provide a clear return-to-work date and time.

The 12 people already reinstated into vacancies do not have an ongoing denial-of-reinstatement issue if they were promptly reinstated. But if any of them were delayed after June 25 or placed in inferior jobs, back pay or wage differential exposure may still exist for the period of delay or loss.

## C. Back pay runs from June 25

Under Severn Rule 7, back pay for unlawfully denied reinstatement runs from the unconditional return offer, subject to mitigation.

Therefore, back pay begins on **June 25** for each nonmisconduct striker whom Ironvale did not timely reinstate.

Back pay is not automatically limited to the period between June 25 and some later date. It continues until the employee is reinstated, subject to mitigation.

## D. Mitigation

Ironvale may reduce back pay by showing that the striker:

- earned interim wages; or
- could have earned wages through reasonable mitigation.

The burden will generally be on the employer to prove mitigation, but the employee must make reasonable efforts to minimize losses. Ironvale should not simply speculate about mitigation. It should request documentation, give notice of any deductions, and calculate back pay in a transparent way.

## E. Back pay for the misconduct individuals

If Ironvale lawfully denies reinstatement to the bottle-thrower or the threat-maker based on serious strike misconduct, those individuals likely lose reinstatement rights individually and would not receive reinstatement back pay.

If Ironvale cannot make an individualized, credible finding of serious misconduct, it must reinstate them and back pay will run.

The third individual, who briefly blocked the entrance and moved when told, should be treated as a nonmisconduct striker and is entitled to reinstatement and back pay.

## F. Exposure summary

| Group | Reinstatement? | Back pay? |
|---|---:|---:|
| 12 already timely reinstated into vacancies | Already reinstated | Generally none, unless delayed or wage loss |
| Remaining nonmisconduct strikers | Yes, immediately | Yes, from June 25, subject to mitigation |
| Bottle-thrower | Only if no valid individualized misconduct finding | Only if reinstatement right not lawfully forfeited |
| Recorded threat-maker | Only if no valid individualized misconduct finding | Only if reinstatement right not lawfully forfeited |
| Brief entrance blocker | Yes | Yes, from June 25, subject to mitigation |

# 7. The three misconduct cases must be handled individually

Severn Rule 9 is clear: Ironvale should not terminate or deny reinstatement to the entire group based on alleged misconduct by identified individuals. Each named case must be evaluated separately.

## A. Bottle-thrower who broke a replacement worker’s car window

The video shows one striker throwing a bottle that broke a replacement worker’s car window.

That conduct likely falls within serious strike misconduct. Severn Rule 6 identifies “deliberate property destruction” and violence as conduct that may cause an individual to lose reinstatement rights.

### Likely result

If Ironvale investigates and confirms the video and context, it may lawfully deny reinstatement to that individual and may even terminate the employment relationship.

### Required process

Ironvale should not rely solely on the video. It should:

1. preserve the video and any related evidence;
2. investigate the incident;
3. notify the individual of the specific allegations;
4. give the individual a meaningful opportunity to respond;
5. make a documented decision based on credible evidence; and
6. state the grounds for denial.

If the evidence is credible, the individual’s reinstatement rights may be forfeited individually. The rest of the strikers are unaffected.

## B. Striker who made a recorded threat to “break your jaw”

A recorded threat to “break your jaw” is likely a credible threat, especially if directed at a replacement worker and made in the context of a work stoppage.

Severn Rule 6 identifies credible threats as conduct that may cause an individual to lose reinstatement rights.

### Likely result

If Ironvale determines the threat was credible in context, it may lawfully deny reinstatement to that individual.

### Required process

Again, the decision must be individualized. Ironvale should:

1. preserve the recording;
2. determine who made the threat, to whom, and in what context;
3. assess credibility under an objective standard;
4. give the individual notice and an opportunity to respond;
5. document the decision; and
6. ensure the decision is not based on speculation or group guilt.

If the threat is found credible, reinstatement rights may be forfeited for that individual only.

## C. Striker who blocked a truck entrance for seven minutes and moved when police instructed

The third individual stood with a group blocking a truck entrance for seven minutes but moved when police instructed the group to clear.

Severn Rule 6 specifically states that peaceful picketing, chanting, and blocking an entrance briefly without violence do **not** automatically forfeit reinstatement rights.

Seven minutes appears brief, and the individual moved when instructed. There is no indication of violence, property destruction, or credible threats.

### Likely result

This individual should be reinstated with the other nonmisconduct strikers.

Ironvale may have been able to seek a court order or law-enforcement response to the blockage, but that does not automatically strip the individual of reinstatement rights. Absent additional misconduct, Ironvale should not deny reinstatement based on this incident alone.

### Required process

If Ironvale wants to treat this individual differently, it must identify separate, specific, credible misconduct beyond the brief peaceful blockage. Based on the facts given, it has no strong basis.

# 8. Lawful immediate response

## A. For the nonmisconduct strikers

Ironvale should immediately:

1. withdraw the preferential-recall treatment for nonmisconduct strikers;
2. issue written reinstatement notices to all nonmisconduct strikers;
3. reinstate them to their former jobs or substantially equivalent jobs;
4. restore wages, including the evening differential where applicable;
5. restore benefits and seniority rights as required;
6. give clear return-to-work instructions; and
7. calculate and pay back pay from June 25, subject to documented mitigation.

Ironvale should not condition reinstatement on any requirement that undermines the unconditional return offer.

## B. For the replacements

Because the strike is being treated as unfair-practice, the replacements cannot be treated as permanent replacements for purposes of denying reinstatement.

Ironvale should:

1. notify the replacements that their positions may be vacated to reinstate returning strikers;
2. displace replacements to the extent necessary to make room for nonmisconduct strikers;
3. reassign replacements to genuinely open positions, if any exist, without blocking reinstatement;
4. give reasonable notice where practicable; and
5. avoid any conduct that could be viewed as retaliatory or coercive toward either strikers or replacements.

If there are more nonmisconduct strikers than positions that can be restored by displacing replacements, Ironvale cannot avoid liability by leaving them on a recall list. It should immediately consult with the union and, if necessary, the appropriate Severn labor authority about a restoration plan. Back pay exposure for unlawfully denied work may continue until the issue is resolved, subject to mitigation.

## C. For the bargaining process

Ironvale should immediately:

1. restore the $1.75 evening-shift differential;
2. confirm in writing that the differential is restored;
3. cease any further unilateral changes during bargaining;
4. resume bargaining promptly;
5. bargain in good faith over the wage increase and any other outstanding issues; and
6. avoid any statements or actions suggesting that the union will be penalized for having struck or filed charges.

The differential was unlawfully eliminated. The remedy is not merely to “bargain over” it while withholding the pay. Ironvale should restore the status quo and then bargain in good faith about any future changes.

The June 12 union offer showed that restoration of the differential and resumption of wage bargaining were the union’s conditions for ending the strike. Ironvale’s immediate acceptance of that framework would reduce the risk of continued back pay and further unfair-practice exposure.

---

# 9. Concrete strategy for Ironvale

Ironvale should not spend resources trying to defend the strike as “economic” based on the label alone. The contemporaneous evidence makes that defense weak.

The better strategy is to **concede the legal significance of the June 3 violation, stop the ongoing harm, and manage the remedy**.

## Recommended action plan

### Step 1: Restore the differential immediately

Send a written notice to the union and affected employees that the evening-shift differential is restored. This cures the continuing unilateral-change violation and removes a major source of ongoing dispute.

### Step 2: Issue immediate reinstatement notices

Send written reinstatement notices to all nonmisconduct strikers, including the brief entrance-blocker. State the return date, position, wage, and benefits. Make clear that reinstatement is unconditional.

### Step 3: Displace replacements as necessary

Notify the replacements that returning strikers have reinstatement rights. Displace replacements only to the extent necessary to reinstate nonmisconduct strikers. If replacements can be placed in genuinely open positions, do so, but do not use them to block reinstatement.

### Step 4: Calculate back pay promptly

For each nonmisconduct striker not timely reinstated, calculate back pay from June 25 to the date of actual reinstatement. Deduct only documented, reasonable mitigation. Provide a clear calculation and pay promptly or propose a transparent settlement.

### Step 5: Handle the two serious misconduct cases individually

For the bottle-thrower and the threat-maker:

- preserve evidence;
- conduct a documented investigation;
- provide notice and opportunity to respond;
- make individualized findings; and
- deny reinstatement only if the evidence supports serious misconduct.

For the brief entrance-blocker:

- reinstate;
- provide back pay;
- do not treat the seven-minute blockage as an automatic forfeiture.

### Step 6: Resume bargaining in good faith

Schedule bargaining promptly. Restore the differential before or at the start of bargaining. Negotiate the wage increase and any other outstanding issues in good faith. Avoid further unilateral changes.

### Step 7: Consider a global settlement

A settlement could include:

- restoration of the differential;
- immediate reinstatement of all nonmisconduct strikers;
- payment of back pay with agreed mitigation deductions;
- individualized misconduct hearings with binding or final outcomes;
- no admission of liability if Ironvale wants to preserve its position; and
- a compliance commitment regarding future bargaining.

A settlement may reduce litigation risk, stop daily back-pay accrual, and avoid the adverse optics of continued denial of reinstatement.

### Step 8: Implement compliance safeguards

Ironvale should also take steps to avoid repeating the problem:

- train managers and bargaining representatives on unilateral-change rules;
- prohibit pay changes during bargaining without union agreement;
- create a written emergency-exception protocol;
- document any claimed emergency before implementing it;
- preserve bargaining and strike-related communications; and
- avoid internal statements that could be read as coercive.

---

# Final recommendation

Ironvale’s current position—treating the strike as economic and retaining permanent replacements—is not sustainable on these facts. The June 3 differential cut was unlawful, the strike was mixed-motive but materially caused or prolonged by that violation, and the June 25 unconditional return offer triggered immediate reinstatement rights for nonmisconduct strikers.

Ironvale should immediately:

1. restore the evening-shift differential;  
2. reinstate all nonmisconduct strikers;  
3. displace replacements as necessary;  
4. pay back pay from June 25 subject to mitigation;  
5. individually evaluate the two serious misconduct cases;  
6. reinstate the brief entrance-blocker; and  
7. resume good-faith bargaining.

That approach is more defensible than continuing to rely on an “economic strike” label that the contemporaneous evidence is likely to reject.
