One department in particular has had almost 100% turnover twice in the past 3 years. 3 people left voluntarily within a month of each other, the department's manager left a few months before that, and each person that left advised HR/upper management of the department supervisor's inability to effectively run the department and support the employees. Instead of taking all of these people seriously (including the remaining employees, many of whom echoed the sentiments of the people who gave their notice), management then FIRED 2 additional employees, claiming they were too negative.
In addition to horrible management, you hardly get any days off (which doesn't make sense for an employment association claiming to use best practices), and the benefits are different depending on which state you work in, which doesn't really make sense.
