I was recently terminated by my employer over an HR issue. The details are sketchy, as I haven't even been given a full accounting, but apparently someone complained about swearing. I was actually planning on quitting anyway, and had already been in contact with other companies. But now that they beat me to the punch, what am I obligated to divulge when a prospective employers asks why I left or am leaving? The termination was bogus enough that I am contacting a lawyer to discuss, so that issue isn't even fully resolved.
