The 1. of May: worker's day

This day is the 1. of May and is the worker's day. I think this day means "labour, effort and fairness". Therefore this day has been given away to the workers. People say "the workers day is a public holiday everywere" but workers don't have a public holiday. Civil servants, students and deputies do have a holiday but waiters don't have a holiday. I dont understand this statement.
