If you don't get retro pay then use your vacation time like the rest of us do.
Why the hell should you or anyone get payed to sit on your ass at home??
If you are at work then you should get payed.
If I was sitting on my ass at home I wouldn't expect a paycheck.
That, however, is not the case. I'm here in the office making sure that your parents are getting their retirement checks, all the while TRUSTING CONGRESS to pay me for my skills and services after they finish their little T-Party hissy-fit.
