Pros

Good benefits Lots of time off Flexible hours Can work remote during bad weather

Cons

Managers overwork employees Large on favoritism Backstabbing management Unstable employees are not disciplined HR is a joke, multiple employees report managers who are not reprimanded for bad treatment and behavior toward their employees Turnover is huge in finance, no one trains employees and expect them to know what they’re doing I could go on

Pros

Good company that cares about their products and the welfare of the animals.

Cons

I was mentally abused by the management at this office. I went to HR and nothing happened. I was forced to do menial tasks, sign a paper saying I was on probation, was told not to make friends, was threatened that I would never be promoted, I could go on and on. If you try to transfer departments, the management will target you and never promote you to a higher role I went to the HR department and nothing was done. I was forced to quit after having anxiety attacks nearly daily at the thought I would have to go back to work.
