Mate, I browsed your profile and you live in Australia. Why would you want to spend the better, sunnier part of the day inside of an office? How is that "quality of life" better than spending an hour or so to play some basketball with some friends?
> Of course we still do team building activities, but these are occastional off sites. Or optional after work things (drinks, workouts, indoor football etc)
So it's not okay to intrude on "work" by playing an occasional basketball game, but it is okay to push mandatory work activities that eat up one's personal time? Also, if you think those activities are not work, you are deluding yourself -- no one likes to hang out with their boss or coworkers for "fun" after work hours.
