If you want to get ahead, it is rarely based on how you do your job, it's who you are friends with. The boys club network is very alive at WU, at least in compliance. Is every department in compliance like that? No, in some of them it only matters if you are willing to work tons of extra hours for no extra pay, and kiss up to certain people.
I did work with some great people here. I also worked in a position that I loved, and was very good at - only to have to leave that department and position because I was told I would never get promoted, because the Director's buddy was going to get it instead (and that my experience didn't matter). And, mine is not the first or last story to have that ending.
Finally, just know that as a compliance employee, you will be treated as a minion/peasant by the CEO and his people. After all, they all went to a brand new glitzy building, and stuck compliance a mile away in an old building that has seen better days.
Salary and bonus %'s will vary by who you know and, depending on the department in compliance, what your gender is.
And yes, the CCO is aware of all of this and chooses to not do anything about it.
