The Unilateral Shift Change and Two Suspensions

Hours of work and shift schedules are core terms and conditions of employment and are ordinarily mandatory subjects. Each of the director's arguments fails on its own terms:

• Management rights. A management-rights clause grants authority to direct operations; it does not waive the duty to bargain over mandatory subjects unless the waiver is clear and unmistakable. Article 12 says schedules are set 'subject to this Agreement' - language that cuts against unilateral action, not for it.
• Zipper clause. A zipper or waiver clause typically waives proposals not raised during bargaining; it is generally not a defense to a mid-term unilateral change on a mandatory subject.
• Past practice. Thirty years of a consistent 7:00 a.m. start, accepted by both parties, fills the gap the contract leaves and becomes an enforceable condition of employment. A past practice can be changed through bargaining or through a clear, announced repudiation followed by consistent application - not by a memo issued ten days out.
• Effects bargaining. Even where an employer retains the right to decide, it must bargain over implementation effects: notice, reporting, leave accrual, heat protections, and child-care or transit impacts on employees.

FLSA check: the 30-minute unpaid lunch is lawful only if employees are completely relieved of duty. Replacing it with two paid 15-minute breaks keeps the day at eight paid hours, so cost should be neutral - but confirm no employee now crosses 40 hours and that any on-call lunch was already being paid. Unilateral implementation exposes the employer to a prohibited-practice finding, a bargaining order, status quo ante relief, and make-whole remedies.

The general rule is obey now, grieve later: an employee who disagrees with a directive follows it and challenges it through the grievance procedure, unless the order is unlawful or creates an imminent safety hazard. Reporting at 7:00 a.m. does not meet that exception, so the refusal is not automatically protected.

But just cause is evaluated as a whole, and the employer's own conduct weakens the case:

• Notice. Was the memo actually received and acknowledged by these two employees, and were they told the change was effective and that refusal would be treated as insubordination?
• Clarity. The memo changed both start time and meal-period structure; ambiguity about whether the lunch period still applied could reasonably have confused employees.
• Consistency. Were the other 20 employees who also reported at 7:00 a.m. disciplined? If not, the employer has created a disparate-treatment defense on the first day.
• Proportionality. A one-day suspension for a first offense rooted in a contract dispute is a heavy penalty where no safety or property consequence occurred.

Recommendation: hold the suspensions in abeyance pending the grievance, and consider converting them to written reprimands with back pay for the lost day. Do not escalate. Meanwhile, issue a clear written directive restating the effective schedule and the expectation of compliance, with signed acknowledgment, so any future refusal is unambiguous. Preserve the memo, the distribution list, and any acknowledgment forms for the arbitration file.

Days 1-3: Formally suspend the memo's implementation with a written notice to the union. Concede nothing about the merits - the notice should say the employer is pausing to bargain and will resume the change after bargaining or impasse per the agreement. Withdraw the suspensions pending grievance review. Issue an interim heat-illness plan covering water, shade, rest cycles, acclimatization for new employees, and supervisor monitoring - this addresses the director's legitimate safety concern immediately and removes it as a bargaining chip.

Days 4-14: Schedule bargaining sessions and identify the union's actual interests (start time, notification lead time, break structure, effects on leave accrual and overtime). Consider a temporary memorandum of understanding for the remainder of the heat season, with the permanent schedule addressed at successor negotiations.

Days 15-30: Bargain to agreement or impasse per the CBA; train supervisors on the new terms and on the duty to bargain; document everything.

Risks if the director refuses: a prohibited-practice charge with a bargaining order, status quo ante relief, and make-whole liability; an arbitration award overturning the suspensions and any discipline issued under the unchallenged memo; a credibility problem for management in the successor contract talks, where the union will cite the episode; and a safety backlash if employees read the heat plan as retaliation-driven. HR's job is to give the director the lawful path, in writing, and make sure the general manager sees the exposure.
