It has come to the union's attention that members in certain departments around campus are being asked to sign confidentiality agreements. It is the union's opinion that members should not sign these documents (or any others that they may ask you to sign).
All terms of your employment are covered by the collective agreement and members should not sign or agree to anything outside of that. Signing any agreement could possibly result in you giving up rights and protections that the collective agreement gives you. If the employer has issues such as this that they wish to address, they should be bringing those issues to the bargaining table.
So the advice from the union is not to sign any such forms or agreements. If you are pressured or ordered to sign by management, you should sign your name and next to it state, ”signed under duress”.
