Knowledge is power.
In my career, I have never seen all the people contributing to the birthday of each and every employee of the company. Department wise they will do these parties. The employee who celebrates his birthday will host a party and the people attending may come with a gift. This is how it was happening in the company where I worked for a long time.
It is also a good thing if an employee makes it clear to all at the outset that he/she does not wish to celebrate a birthday and nobody should buy gifts or arrange a party inside the office or outside.
When you make a commitment, you create hope. When you keep a commitment you create trust! ~ John C. Maxwell
I would still appreciate if it was an employees marriage (not anniversary) for which all the 300 can contribute to present a gift to the newly married employee.
