Rank and File: The members of a union.
Ratification: Formal approval of a newly negotiated agreement by vote of the Union members affected.
Ratification Vote: A vote of bargaining unit members to accept or reject a proposed Collective Agreement (or other agreement). Every active member of Local 464 has a say in whether a contract is accepted or rejected.
Retroactive: A change comes into effect on a date that has passed. For example, if the Union negotiates a wage increase during bargaining, you may be owed that increase back to when the Collective Agreement starts.
