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.
For example, imagine that there are 6 people and salary of each person is $1000. They determine via coin flip who is the 1st, 2nd, 3rd, 4th, 5th and 6th. First gets $6000 in the end of the month, in the next month, the second gets $6000 and in 6th month, the 6th person gets $6000. You may ask me how do they live for 6 months without a salary? Family members take care of them. Too many people work for fun because sitting at home is boring for them but they don't have enough money to have fun too.
What is the point of this? I understand that the person who gets all six salaries first will be able to use that money for a while, so it turns out to be an interest-free loan. But for the one who receives their salaries last, they are simply giving their money for someone else to use without any interest. I see no sense in this and I would definitely never take part in something like that. If you know how to manage money and know where to invest it, it is much better to set aside a certain amount every month and let that money work for you and bring you profit.
