I got this friendly reminder from my workplace about Labor Day. I guess they don’t want me to forget and come to work when I shouldn’t be there! The notice includes a little bit of history about Labor Day:
“This is your friendly reminder that we are closed Monday, September 7th in observance of the Labor Day holiday. Please inform all neighbors, friends, and partners with whom you work.
A little Labor Day history:
The holiday originated in 1882 as the Central Labor Union of New York City sought to create "a day off for the working citizens." Congress made Labor Day a federal holiday on June 28, 1894, two months after the May Day Riots of 1894. May 4 was chosen to remember the Haymarket Affair. All 50 U.S. states have made Labor Day a state holiday.
Thank you for your hard work each day. Have a great weekend!”
The Haymarket Riots were an important event in American history, but they are little remembered now. Here’s Wikipedia’s summary of the incident:
“The Haymarket affair (also known as the Haymarket riot or Haymarket massacre) was a disturbance that took place on Tuesday May 4, 1886, [this appears to be the correct date] at the Haymarket Square  in Chicago, and began as a rally in support of striking workers. An unknown person threw a bomb at police as they dispersed the public meeting. The bomb blast and ensuing gunfire resulted in the deaths of eight police officers and an unknown number of civilians.  In the internationally publicized legal proceedings that followed, eight anarchists were tried for murder. Four were put to death, and one committed suicide in prison.”
