I'm a no vote purely on retro. I'm not going to reward the company's bad behavior of dragging a contract out for 4 yrs and making me pay a portion of my own raise. They had 4 yrs to negotiate (2016-2020) in good faith. They drag it out for 4 yrs to make it as painful and costly to me as possible. Enjoy the raise, it will be what you earn for the next 9 yrs.
I want full compounded retro, with NEC match. Period.
