With pay rates, how pay is calculated, less pay for vaca, increased insurance premiums etc, it's thousands of dollars per year. It could easily add up to ten percent. It's not a matter of if you can live on it, it's the principle of being forced to take cuts in pay and qol when the real problems in the company are over-paid under-qualified people in the GO running this place into the ground.
PS. I know extremely wealthy people who kick and scratch over a few bucks even they don't need it or won't miss it. No matter what your financial situation, you want to keep what you've earned.
