Man, does a story like this piss me off. It upset them that they had to pay you commission, a percentage that they orginally agreed on, just for the simple fact that someone was getting alot of money, even though it was just a reflection of the huge amount of money that your work had just made them. If you agree to pay someone x% of every dollar they make you, then what the fuck difference does it make if you're paying that % on $100 or $5,000,000?? That meeting should've been to congratulate you and your boss on a job well done and to inform you both that an extra bonus was being included for the record setting deal, especially since that the fact that it was the most money that they had ever paid someone at once translated to the fact that it was the most money that they had ever made themselves at once!! You just can't make some people happy.
It's like buisness owners get threatened by the fact that someone else might enjoy financial success, especially when they have to write the check for it.... even if that person's work has just made them filthy ass rich 20 times fold!!
I've seen several situations like this myself. Working by the hour and get a shitload of overtime in a pay period, and even though you know that because of the overtime you put in, the person you're working for really cashed in on the job, it still pisses them off to have to cut you that big check. Like, if it was the same amount of money being paid out, just divided over say more people or something, for their same amount of profit being made on whatever work that was done, then it wouldn't bother them one bit.... but having to see someone else be rewarded largely just upsets them.
I swear I've worked for and with people who, if given the option to net 10k a week after payroll the payroll been 5k, or to net 5k a week after payroll but only have to pay their help 1k..... they would choose to make half as much just to save themselves from having to witness others being rewarded with good money!!
I'm glad that your boss didn't sign that stupid, greed laiden fucking contract, and I'm glad he won the lawsuit. If that company didn't decide to do away with those contracts and that entire idea, then I hope they fucking go bankrupt... because that's what assholes with that type of greed and hatred for other's success deserve.
