One thing would be to carefully document your time for a year, including all time spent doing things necessary for your job, like getting paperwork, going over the loads, preflight, guarding the cockpit/entrance, etc., then have your union take the airline to court to pay overtime, like this:

Of course, you'd need deep pockets because the airline would throw everything they could at you, appeal after appeal, etc., but you could probably make a pretty good case for it at the regional level. Make them pay you for the time you are working and any overtime.

Course the union would never support this, which is why you don't really have a union. They don't really have any power because of RLA, so it's more of a dog and pony show.
