I've been with my employer for almost 6 years (full-time). Over the past year, I've had several paychecks returned for non-sufficient funds. When this happens, I take the check directly to my employers bank. More often than not, the check cannot be cashed but if I go daily, eventually I manage to get the check cashed. It has started again and this time I'm having a hard time getting my recent paycheck cashed, the funds are not there. How long must I continue to put up with this, at what point can I file for unemployment and what kind of documentation do I need in order to file a claim?
