I disagree, unless the stealing was unprovoked. I admit to stealing time in the past, only because there's a FT sup that actually goes in and changes my time card and removes minutes from me. I know he does it and he even admitted to it at one time. Since then he stoppe doing it when I complained with the union and threatened further action, but foudn other ways to harrass me. So there are undoubtably cases where you should steal back.
2 wrongs don't make it right. You supposedly stealing time means you haved stooped to his low level of human behavior.
