Pros

Full time position 40 hrs . weekly

Cons

Employees work against you unless you are part of the mean click and Reporting a Bullying issue just equals more untrue write ups and more bullying from team leaders and Managers.I have never had so many write ups in my 25 years in the Medical field. I was forced out of a job that I enjoyed.
