Bad management team and a bad company politics - Manager Vituity Employee Review

MedAmerica (MA) hires a lot of entry-level individuals and pays at the lowest rate possible! They target hard-working individuals that will give 200%+, and MA will keep on piling work on top of work (their work-life balance motto is a joke, take a look at the head of HR! She works insane hours, including at 3am!). This results in the workforce quickly becoming bitter and feeling taken advantage of due to the HUGE discrepancy between pay and productivity. This leads to crazy turn-over (which is now a chronic disease for MA). In addition, those that have management positions are easily threaten and will "play dirty" to remove the "potential threat", actually destroying that person's potential at MA. Management appointments are given to those that do not pose a threat (and those that are friends with them - there is a clique of the management team that is so apparent). When new managers/leaders are hired from outside, their potential for success at MA is also very, very low as it is hard to break into the clique of managers (who are very powerful). I came in as an entry-level employee and quickly moved up the ranks of manager. However, it was clear that the more I performed well and the more I learned, the more I became a threat - and once you are targeted, those with power will do anything possible to destroy you. I am speaking from experience. If you want to succeed as a manager within MA, you have to be ok being a "puppet manager" and you must always be passive and submissive to those managers that are part of the clique (those that have been there 10-20 years). In conclusion, the culture within the management team is similar to the culture of a "mean girl" clique in high school...I have to mention that some of the management is known for not performing or producing much work. These people have stayed in their jobs because of their relationship ("friendship") with those on top.
