The Department of Labor's "80/20/30 Rule" for tipped employees is dead.
1. Tip-producing — Work that "provides service to customers for which tipped employees receive tips."
2. Directly supporting — Work "performed in preparation of or to otherwise assist tip-producing customer service work." Think rolling silverware, filling saltshakers, or cutting garnishes.
3. Not part of the tipped occupation — Work that is neither tip-producing nor directly supporting, such as cleaning bathrooms.
