He has the right to do this, but he shouldn't complain about the consequences of his actions. We will see how this plays out.
@CC1974:
My husband and I talked about this yesterday, DH thought he should be fired. I disagreed saying he has the right to protest this way. But just because he has the "right" to do something, doesn't always mean it's the right thing to do. Like you, I wonder where he will take it from here. 4951
