You can enforce such rules on your own, by slowly trimming down after-hours "work" (since it is unpaid, it's not work to me). You can compensate this with very good time management and always being on time/reading up on meeting agendas.

Eventually they get used to this status quo and nobody will even question it anymore in your case. It might take you a few years, but it pays off in the end I think.
