Yeah. I'm starting to sense a pattern...
Maybe it is time to update your resume?
Yikes! I once worked for a company that did that, nully. It was no fun guessing if or when payday would arrive. That was made more interesting by the visit every month or so by the corporate finance guy who would spread the rumor that the company was about to go under.
That was 15 years ago. The company still survives, still has paydays when "the checks didn't come"/"payroll department screwed up"/"the dog ate the checks" excuses are rolled out, and still has the finance guy bring monthly bad news of impending doom.
I hope that your situation improves rapidly.
