5. Labor Day history:
The holiday grew out of worker protests and remembrance days in the late 19th century and became a federal holiday under President Grover Cleveland in 1894, following a railroad strike that involved several deaths, 27 states and hundreds of thousands of union members. The legislation creating Labor Day was passed by Congress just six days after the strike ended.
