In my region, salary lotteries are very popular in many workplaces. I don't know what's the exact English term for his but we call it that name. The purpose of salary lottery is that 5-6 employees collect together and they play lottery. The first winner gets the salary of every worker, in the next months the second winner gets everyone's salary and that's it. There isn't a random winner, everyone gets their salary back but the fate of who is the first person to receive the salary is decided via a simple coin flip.
This is totally absurd, and I wonder why people can be very callous in risking their salaries for lottery purposes that's a sign of indiscipline and an irresponsible act. Things as these ain't meant to be played with especially when you're not sure of your fate in winning and then each month you lose your hard earn salary to lottery all for fun that's totally out of place.
