I agree, but I Ry don’t think complying will be advantageous to OP either. Not nyo do they get less prep time out of it, it’s also removing from the benefits given by the contract.

There’s also a chance that if they’re firm on their action and make it clear they are going to follow the contract, the people running the meeting may stop doing it early days they work, as they need to recap the entire thing once they are on the clock anyway.

Regardless I don’t think OP should let it get to them, my old work was that way, everyone was expected to clock in early and work late, I stood firm and even made some comments on how I habe a life outside of work and I follow my shift, they eventually left me alone.

There’s no winning if you cave and just follow the mantra all you do is come out with less. Regardless of what the rest of the workers think.
