Sexual harassment issues, old boys club, long hours, horrible pay, bottom of the barrel benefits, empty promises, outdated practices, failure to deliver, huge lack of employee resources.
After working in the Managed Services department for a decade, I can tell you that this place is run horribly.
We were often expected to work 50+ hours with no compensation.
The worst people somehow get promoted to management, and even openly brag about how many times they've been reported to HR. One manager (who is married and has kids) would "joke" about how he'd do favors for female employees if they dated him.
There is a strong inner circle that gets promoted more often, and refusal to participate completely eliminates your chances at advancing.
One employee made racist remarks at another, and when it was reported, the victim was punished and the harasser was promoted to a manager. Another time an employee made a racist joke, and when I reported them, I was told to "stop picking on him."
I was paid well under market value for my position, and when I asked if I could be compensated fairly (new hires made twice as much), I was told by my boss to "get used to eating peanut butter sandwiches" to save money.
The health benefits are expensive and cover almost nothing. One year I had to pay the maximum out of pocket ($15,000) because none of it was covered even though the provider was in network. They do an employee survey every year, and one of the consistently most reported problems is benefits, but they do nothing to change them.
I was once kept in limbo of being promised a promotion, but they would constantly tell me "it's not in the budget," then spend stupid money on new chairs, or bigger TVs in my office.
We would often joke that CDW shouldn't have customers because of their complete inability to deliver on anything. The NOC in Managed Services gets an absurd amount of tickets, and instead of focusing on ticket reduction (most of them are meaningless noise), they keep adding on. They also introduce new services that do nothing, but cost money for some reason. They don't sufficiently staff any team, so everyone is spread so thin that you're constantly overworked, and you're treated like garbage if you have a problem with it.
They constantly tout their diversity and inclusion, but women and minorities are treated like crap here, to the extent that it can be an aggressive environment. They once received a report of rampant sexual harassment by managers, and instead of punishing them, they held a series of meetings to listen to the problems women had, and then did nothing with them. But that's CDW, appear to care, but never do anything to prove it.
I could go on and on about this, but I will summarize everything by saying "never work here." I say that as someone who was promoted many times, and was overall treated better than most people.
