Pros
buy a vacation week, some opportunity to work from home in some departments
Cons
Over reliance on UK EEs that cost the company a ton of money. Should build US capability with full time US EEs, not UK EEs or consultants. Low skilled people whether from UK or US. Not many Ivy League educated or best practices happening here. People work hard (long hours) but not smart (manual fixes to reports, cutting pieces of paper on papercutters, buying own supplies). I doubt the Brit invasion will stop because of Brexit. I was told by one seemingly well-regarded UK employee, "I don't care about metrics ... I stay far away from numbers as possible" and things like, "You Americans don't know how to make tea", and "You Americans are too uptight" (in response to advising a UK colleague that perhaps they don't want to use a game called, "Chinese whispering game" which has negative connotations). See? elitist attitude. My department is run on fear.
