My sister was suspended from work after being arrested in the parking lot of her job. Her and some coworkers went to eat after their shift ended. When she was on her way to drop them off at the parking lot of their job she was arrested as soon as she parked for some warrants. They followed her from the street they were not there waiting on her. She was told she cannot return to work until after her court date. Is this legal? She lives in Michigan.
