I put in my two week notice due to the asking to be moved to a different department multiple times (due to stress and workload) but not being accommodated. Once I did this, my employer removed all my access and told me they were accepting an early resignation (which I did not agree to but had no choice). I filed for unemployment and it was denied because the employer is now saying that I was turning other employees against them for including them on my resignation letter.
Can they do this? Also, should I allow potential employers to contact the former employer?
