Employees have rights during investigatory meeting/interviews. These rights are called
“Weingarten Rights” based on a 1975 Supreme Court decision.
If called into a meeting with your supervisor or manager to investigate a situation which might result in discipline, you have specific representational rights and should state:
“If this discussion could in any way lead to my being disciplined or terminated, I respectfully request that my UPSC steward be present at the meeting. Without representation present, I choose not to respond to any questions or statements.”
