I remember the anxiety that not getting paid produces. Years ago, Just Ron worked for an outfit and his paychecks started bouncing. Once, it was a check for less than $10 - can you imagine a business not having a lousy $10 in the account? Worse, he cashed it at the university where he was studying and ended up on their bad check list. He couldn't pay any of his student fees by check after that - had to get a money order or pay cash.
I do hope you find a good job that values you and treats you right.
