I guess I'm confused Are you or are you not an ALPA member
If your at JB and your "paying dues", what for?? If it sounds like I'm coming down hard it is only to make the point, "If you don't have the right/choose not to have the right, to bargain" you get what you get, not what you negotiate. And don't give me this crap about "bring down the house" by just being union, you guys will decide your contract, its terms and what you think your worth, not some lawyer in DC. The company dribble you're likely to hear when and if you vote on unionisation is pure BS. YOU decide your fate, YOU decide your work rules (if any), YOU decide what YOUR worth. Not us, or some payed mouthpiece from Washington, You. The power is and always will be in your hands, if you chose so.
If you think your present salary is fair considering the profitability of your company, so be it, put it in a contract. You wouldn't buy a house without negotiating the price, or probably a car, why would you do any less with your career. Good luck
