Awful Culture, Stagnant Position

Pros

There wasn't that much good about this place, I was very relieved to get out of there.

Cons

-Hands down the worst culture I have ever seen, and am pretty sure I will ever see. The type of place where your teammates will talk crap about someone when he/she leaves the desk for 5min to get a cup of coffee. -Profanity & dirty language are the norm. -No career training or continuing education. -Work load is beastly; I felt sorry for lots of the people there, and questioned how they stay married? -Their 24hr desks, which at most companies are staffed by 12 people, thus allowing for adequate training, relief, and a good work life balance, are staffed by only 3-4 people. -Towards the end of my tenure they they tried to institute a training week for the 24hr desks, but ended up with a dumpster fire of a solution: One lucky person on their week off will come in "train" on all nights, all weekends and all holidays. Though there was no set training to be had...This was their solution/punishment for a training week. -Did I mention the work life balance is deplorable?

Pros

Decent pay and good health insurance

Cons

Over worked, no such thing as "work life balance"constantly reducing staff but yet requiring more out of those that are left, will work you non stop until you either quit or have a heart attack. More than two people I know have had heart attacks while working there because of the stress

Toxic place to work

Anonymous employee

Pros

Benefits are great, that is it. Don't work here. Avoid this place like the plague. Please avoid unless you want stress related health issues.

Cons

The entire environment is toxic. So many people have health issues because they are so stressed and over worked. The execs, management, HR and any other group that can do anything about it doesn't care. They constantly blame the workers but the real problem is management. They don't give any direction then tell you what a horrible job your doing (or how you aren't adding any value). The company is a complete joke and the stock prices match.
