What supplement are you? Mine has this exact language so don’t go bashing the union, get to a meeting and start reading your contract. You want a quick fix and sometimes things take time.
From Metro Philly Supplement:
The Employer shall have the right to require employees to take a meal period of one (1) hour. The Employer may direct any employ- ee to work all or part of his/her one (1) hour meal period, in which event the employee shall receive twenty (20) minutes to eat on Em- ployer’s time and the employee may not be dismissed one (1) hour early but must be worked to the employee’s regular quitting time, producing a minimum of one (1) hour of overtime pay.
If they force you to skip here you get one hour of OT for the price of 40 mins.
