If there is language in an article that is along the lines of “until the expiration of the agreement”, does that mean that whatever is contained in that article is no longer legally binding once a contract expires? I feel like that should be obvious, but my union rep seems to think that’s not the case. I do know that terms and conditions of a CBA are to continue under an expired contract (besides strikes/lockouts) but if that language lives in the document, then is that how an employer can get around maintaining whatever benefit it’s tied to?

I feel like I read a labornotes article that spoke to this but I CANNOT find it. If anyone can help I would be grateful!
