Employees are entitled to have a Union representative present during an investigatory interview that may lead to discipline. Management has no obligation to inform you of this right. It is up to you to assert your right to Union representation.
The Union representative helps protect the employee from coercion or intimidation, and serves as an advocate and a witness to what occurs in the meeting.
Remember, if you are called into a meeting with any management representative and have reason to believe that disciplinary action may result, read them your Weingarten rights.
“If this discussion could in any way lead to my being disciplined or terminated, or affect my personal working conditions, I respectfully request that my union representative, officer, or steward be present at this meeting. Until my representative arrives, I choose not to participate in this discussion.”
