Very poor management, after you have completed training/academy you are left on your own with no help offered or any guidelines...
Team leaders don't want to do anything, when you ask for help it seems like the end of the world for them... constantly stepping on egg shells because you don't want to annoy them even though you've just come off academy/training. So sometimes you have to struggle unless you want to cause a scene.
The job itself is soul destroying. Having customers scream at you everyday can be very de motivating, the stress of the targets can be too much alone, having negative team briefs because certain people/team aren't hitting their targets along with not being quick enough to get off a call/productivity can really put a downer on your work life.
The HR structure on illnesses, if your prone to getting ill, if you have a illness you get a recorded discussion and bonus taken away from you, your third illness within your probationary period they will decide to keep you on board or let you go, along with that with the flea that I once found on my desk I'm not surprised the staff get ill.
