I'm so glad you were able to finally get rid of that person-that is wonderful. Once my curiosity about a new hire in my department at a company I worked for uncovered some very strange and alarming things. I went snooping further, and found that they were indeed true. I went to my supervisor, who was the owner of the company and told him that not only was this person not what she claimed to be professionally, she wasn't even WHO she claimed, had two other alaises besides the one she was currently using and had a felony theft warrant from a company she had worked for in another state. He didn't believe me, was completely charmed by her and asked me to get along with her and not listen to gossip. I found another job within the month and left there in disgust after having worked there for nearly 8 years. Less than a year later, this imposter had brought the company to the edge of bankruptcy, the owner was sued for non-payment of payroll taxes and false representation of that woman's credentials to clients. The con artist/imposter hit the road and disappeared and the company went under-I still howl with glee every time I think about it 10 years later-enjoy your shadenfreude...
Lordy, you have to wonder how places stay in business if people are tipped off to shadiness and stick with the accused shady character. i know if someone tipped off xshub to a bad'un, he might not fire them on the spot, but he would definitely have them under a microscope and be looking for a false move thereafter.
People are so dang gullible.
