Teleperformance review: improper work site! 5

It's a true shame how unfair some establishments are!
I worked at teleperformace for two yrs and loved my job! They were very laid back as long as you completed your assighned work and I truly loved how they seemed to appreciate their staff, I also loved the training they provided we learned about the products in fun ways and I seemed to learn alot! However, after a yr things seem to do a complete flip and with new adjustments and things got strict which is fine I would try my best to adjust, when they started to not appreciate their employees and scare tactics of lay offs and a accm who yelled in her office while we were on calls with customers was very unprofessional very! I was trying my best through theses obstacles and I got along well with my supervisors making 100's on qa's and trying to get involved and then my attendance wasnt a 100 percent due to sickness and sparingly personal issues but I always made up my time when I could. Then I got a supervisor that was really unfortunatley immature, rude and unthankful the supervisor never really told me good job after I made 100 after 100 and when I did anything wrong it was magnified to great lengths overdramatically! I was unliked by an unfair sup still I tried and then she told me one day that I wasnt fired but like suspended I guess about a call that I was supposedly rude to client to even though I was qa'd and on my score nothing about being unfriendly? I tried to get attention of a once consederate accm but she felt it was like I was making a issue of nothing! Very saddend I left they called me back but had me sign a piece a paper... So I was upset but in our economy needed a job so even though they sus and were like not giving me job security my sup told me "we will call you back to work maybe" that to me was ridicuolous! However things seemed to brighten as I got a new sup who said I was making the best scores on her team and I loved going to work again! I felt motivated it was nice! Then after alotta 100 scores and suffient attendance I was doing so well but my team all had one new score that was failing unfortunatley, the crazy part was that they all kept their jobs but I was let go which really bothered me and it was all because of that paper I signed! Whats really crazy is the sup I had got fired from the mobile phone company and got hired for another one. I was not the only one that didn't understand this and I hope I still can do something about this!
