In short my workplace offered a monetary incentive for achieving targets that they would tack onto your monthly salary. We work with customers, so any target achieved already depends on how the client feels on a given day. The target is relatively hard, if you are just short of reaching the incentive target you're entered into a raffle of X amount of money against the rest of the company so you're still “possibly getting something”. The actual incentive money is a good chunk for a pretty low salary.
They really didn't expect people to perform this well within the first month of it being introduced, because they are now scrambling to find technicalities for why certain people don't actually qualify for the money. It's yet to be seen if and how many will have it taken away but feels rotten af.
