My coworker showed up an hour late, meaning he is working 6 and 1/2 hours instead of 7 and 1/2. Union rules state that anyone working over 6 hours gets one 15 and one 30. Management refused to give him the 15. The coworker in question doesn’t want to bring it up because he doesn’t want to cause problems. But it upset me because the managers like to follow the breaks to a T and blame the union when it’s convenient for them. But then this happens and they are acting like union rules are a suggestion. So my question is, can I go to the union about this situation? Or is it something that my coworker would have to bring up?
