You must be in a Right To Work state with weak union representation if they have you believing that you can be disciplined for not signing something, or that you have no choice but to bend over and take such harassment.
Half the drivers in my building have our local union's Business Agent on speed dial. If the company even
tried pulling crap like that here our BA would be up in the DM's office ripping him a new
within an hour.
I have always gotten a kick out of seeing what happens when the company transfers upper-level management out to here from RTW places like Georgia or Mississippi. They talk funny, they cant handle the weather, and they
really cant handle working in a strong pro-union enviornment where the employees know their rights and aren't afraid to stand up for them. They are used to just walking all over their people and intimidating them and treating them like cattle. They look like a deer in the headlights the first time a BA or a shop steward gets up in their face and confronts them, and it finally dawns on them that the contract is something they will actually have to start
following now.
