While federal law does not require that a company have a bulletin board, the federal government, as well as most states, requires that certain official notices be posted conspicuously in the workplace. Failure to do so may result in fines. Bulletin boards also serve as the most basic means of communicating with employees, including legally required postings and general interest information posted by employees. Union contracts often require bulletin board space be provided for use by the union. Employers should have a written policy on the use of bulletin boards.
