As developers we are really fortunate that we often don't have to put up with this shit, but i have some designer friends (mostly fashion) where the job market isn't nearly as good and they have to go through shit like this all the time, because there is just no alternative. In those cases, if you don't agree with those weekend projects, you will most likely just not get a job because someone else will do it. If you ask for compensation for your time you will most likely hear a mad laugh and a "Nope"
