I inherited two employees years ago. As it turned out, one had just hung on because she burned up her coworker every 5 years. I gave the problem employee the option of quitting on her own terms, or being fired. She quit in a huff and she hasn’t been able to find an office than can put up with her since. She tried bad mouthing the company to everyone and sunder but, really, she had made so many people in the very small industry where my company sits hate her that her words didn’t held water.
