You can have a lot going on at work that makes people turn to cold and indifferent because they want to get work done and deadlines met. Their mental effort is focused on that because that's the priority. Socializing can be a context switch. If the company continuously keeps the pressure on, they just continue on like that until switching jobs. It would be nice if we had more time to relax and socialize as a reward for getting work done early or at a higher quality but the reward for it is often more work, which will quickly turn people cynical. If you are cynical, socializing is very much a chore even though they know you didn't cause it. Essentially, there is a lot to focus on that prevents people from relaxing and socializing. But profits are up, so yay?
