While the complaint seems to be over minor issues and there could be a legitimate explanation from LCC's point of view, readers should know that nation-wide, colleges and universities have a long and well-documented history of exploiting junior faculty, especially part-timers and those on short-term contracts.   

Part-timers are paid very low salaries, denied benefits offered to full-time employees, and are subject to the sometimes bizarre whims of administrators.  If challenged, these administrators have many sneaky ways to retaliate, including strategies designed to reduce class size, which offers them the perfect excuse to terminate an employment contract.

Women and minorities in particular are seen as vulnerable by (usually white, usually male) administrators, and therefore easier to exploit.  Sexual harassment is often a part of the mix, although there are no allegations of that in this case.
