How can I express my opinion about whether or not I am represented by a union?

You have several options. As long as you are not using work time or an inappropriate location where you are interfering with operations, you can make your opinions known.

You can make a decision to sign an authorization card if you are in favor of having a union as your exclusive representative. You may also choose not to sign an authorization card if you are not in favor of it.

If there is an election, you can vote for union representation or you can vote against it.
