Absolutely terrible onboarding process- no training manuals, allowed some team members to train new employees who were clearly shouldn't be training anyone due to bad interpersonal skills.
The pay was awful to begin with, however when I expressed this to my manager after a year, I was assured that I could look forward to the upcoming performance evaluation to ease this worry. Well folks, after getting great scores on my eval, I was rewarded with a $0.26 hourly pay increase, which was frankly a slap in the face. When I pointed out that this 1% pay increase doesn't even keep up with an standard ~3% cost of living increase, I was told if I didn't like it I could find a new job. So not very open to hearing employee concerns.
There was mandatory overtime every winter, before the end of the year. Employees feel forced to work since the pay is so low, but get burnt out easily because of the lack of work-life balance during a time that is already very busy in people's personal lives.
Additionally, the office culture was generally pretty laidback and nice, however during my last six months there, my team got a new manager from the east coast. This became an issue when she tried to deploy rigid, formal, east coast culture on our casual west coast team. Among other things, she made arbitrary changes that I felt were power plays more than anything (such as moving the call center to the middle of the floor where they disrupted everyone) under the guise of "increasing efficiency".
