how dumb do the mang think we are. I got a wrote up with no union person there and when i refuse to sign she ask me why i told that there was no union person there. so she call a person that was in the union which is not right going to file against her.
You have the right to have union representation (steward) or your rep to be present in any situation that involves discipline against you. Also if you were given a C.A.R write up, this has to be done one working day after the "offense" later than that can not to held against you. I'd call your union rep ASAP!
never sign anything unless it's your paycheck. if you get written up for something you can ask to read what they wrote, but you are not entitled to sign anything and they cannot make you sign anything either.
