Yes, I finally got paid for subbing! And it was even on time for one of the time sheets I submitted. The other one, as we already know, was submitted months ago and had to be resubmitted.
Therefore, I have revised my estimation of L, this woman in the subbing department. She didn't completely fail to pay me. All she did was "lose" my mailed in timesheet after telling me that she didn't "like to get them mailed in." (coincidence?) Oh, and she refused to answer any of my emails or phone calls about the matter. And she called to yell at me when I canceled a job because I had a fever. But I did get one of my payments on time.
Maybe I was wrong. Perhaps she's not really really really really, REALLY unprofessional. Maybe she's only really, really really, really unprofessional.
