I worked that day and I wasn't overpaid. And if you were overpaid, what do you expect, to be able to keep the extra money that you aren't entitled to?

W2s were late this year because they switched payroll processing providers partway through the year, and end-of-year calculations were messed up so they had to manually correct them. Would you prefer to have an inaccurate W2 and owe more or less taxes than you paid when you go to file?

Mistakes happen - I'm sure that when you make one, you want some understanding from whoever it is you inconvenience. Boutique operates legitimately by every measure I've seen, and I have no reason to believe that anything like what you describe would be intentional. I don't understand this mindset of extreme inflexibility towards common mistakes that any business could make. I guess you've got unhappy pilots everywhere, though, even if things are generally peachy...
