If a manager tries to gamify your workplace - to play individuals or teams off against one another ("It's just a bit of fun," he'll say, "see who can hit their targets first / smile the most for the customer / etc." I see this more and more now, especially in service-based businesses - I once witnessed a leering monkey of a manager in Costa setting his staff off against one another, running them ragged while he surfed the internet on his phone) - resist it by by adopting 'serious' / over-rigid behaviours; shift into 'no-fun' mode. Equally, you can spanner rigid, over-serious / over-controlling managers by creating your own fun / imaginative internal 'games' that can be acted out in the workplace w/out being seen as overtly insubordinate. Adopt parallel roles / personas, use yr imagination to redecorate / relocate yr workplace, run an internal script in wh/ you're doing something other than your assigned goals.
Seriously, why should you create additional surpluses for managers that they get bonuses for, but you are not rewarded for?
If they treat you like a piece of meat, then fuck 'em.
