Really not sure where to start with this considering how big of a mess Cigna is right now...
There's absolutely no collaboration between various departments, internal processes are convoluted and unnecessarily difficult, everybody who isn't management suffers from no work-life balance, pay raises are negligible...
But the kicker is that if you are good and your manager likes you, it will stop your career in tracks... Not joking... If your manager likes you and knows you're a good worker they'll make sure you stay on their team... After all, you need their okay if you want to move to another position... Good luck getting it...
Plenty more wrong here, but I think anybody reading this gets the gist... Stay away if you can...
