Perhaps it is because I have a very visible impact on my department or maybe because all decision making is done during office hours. The bar is for play and karaoke - not to talk about work. The company culture treats any work discussion during team outings as taboo. You won't be punished for it but you'll be told kindly to shut up and have fun - work will be back again next Monday. Talk about it then. :)

If I had to guess, that probably plays a huge part into why the company doesn't have those sort of problems.
