KNOW YOUR WEINGARTEN RIGHTS!
If you reasonably believe that discipline or other adverse consequences may result from a meeting with a company representative, you have a right to Union representation at that meeting. Unlike Miranda, another landmark Supreme Court case, Weingarten does not require notice at the time of questioning or an investigatory interview. This means that the Employer is not required to inform the employee that he or she has a right to Union representation.
SO YOU MUST REQUEST IT:
"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 the meeting. Without representation, I choose not to answer any questions."
