Can an Employer Change Your Job Without Your Permission?
· 6 minute read · Aaron Beaudry

This is one of the most-asked questions on the floor. Can they just move me. Can they add duties. Can they change my shift. Can they send me to another site.
In a unionized workplace, the starting point is usually management rights. Employers run the operation. They assign work. They set schedules — within the hours-of-work language you actually bargained. They do not need your permission for every change.
That is not the same as “they can do whatever they want.”
Duties
If you are a millwright, they can usually assign millwright work you have not done this month. If they assign you a different classification’s work, or strip your job down to something else, the posting and classification language starts to matter. A slow rewrite of the job is how bargaining-unit work disappears. That is also how contracting out shows up in disguise.
Schedules and location
Shift changes are in the agreement or they are a fight. Notice periods, rotation language, premium pay, and whether the change is temporary all matter. A new site or a new gate can be a reporting-location issue, a travel issue, or a layoff in slow motion. Read the article. Do not argue from memory.
When it becomes a real problem
- The change ignores posting, seniority, or classification language.
- The change is punishment dressed up as an operational need.
- The change collides with a medical restriction — that is accommodation, not “flexibility.”
- The change is really bargaining-unit work leaving the unit.
You do not have to like a change for it to be legal under the agreement. You also do not have to accept a change that breaks the agreement just because a supervisor used a calm voice. Talk to your steward before you refuse the work — refusing is its own article. If it is a contract issue, file a grievance on time and work under protest if that is the safe path in your workplace.
