Had worked for 2 weeks.
Since I weaved in a multiplier effect of 0X for getting below 60%, 2X for 80% & above and 3X for 100%, Z was finally understanding the value of producing quality work. I hoped he would remember for a longer time.
Meanwhile, the points system was helping to keep X’s tantrums, sulks and whines in partial check. He was still giving in to his impulses but trying to keep a lid on it. It was heartening that we had some bargaining chips, not that we thought he was getting easier to deal with.
Well, hope this system would work out at least for a few months, or till we found a new solution.
