Why do the company's annual lottery, first prize, second prize and third prize all operate behind closed doors?

Some awards are specially designed for the needs of the company, just to give back in this way. Some employees need rewards, but they are afraid that others in the same department and team will be unbalanced, which is quite harmonious. Because personal rewards stimulate some people, it is counterproductive to give him a special award, so that others can't say anything about their luck. Some people want to leave their jobs so that they can stay. Some are rewards ... and the rest are for everyone's entertainment. You are the boss, and you will do the same, so don't mind.
