With Labor Day Monday, the unofficial end of summer is here.
While most people celebrate the holiday by taking time off from work, doing a little relaxing, or maybe catching one last day at the pool, it wasn't always that way.
The first observance of Labor Day is believed to have been a parade of 10,000 workers on Sept. 5, 1882, in New York City. Peter J. McGuire, a Carpenters and Joiners Union secretary, organized the event.
By 1893, more than half the states were observing Labor Day in one way or another. Congress passed a bill to establish a federal holiday in 1894. President Grover Cleveland signed the bill soon afterward, designating the first Monday in September as Labor Day.
Here's a look at what's closed in the area.
In observance of the Labor Day holiday, government offices in Pine and Richland townships will be closed.
Northern Tier Library also will be closed, as will Allegheny County, state and federal offices and courts. Banks and liquor stores will not be open either.
U.S. Postal Service facilities will be closed for retail transactions. There will be no regular mail delivery and limited collection runs will be conducted throughout Pittsburgh and the Western Pennsylvania District.
Express Mail however, is delivered 365 days a year and will be delivered.
Vogel Disposal Service Inc., which collects trash and recycling for both townships, will be closed Monday. Trash and recycling collection will be delayed one day this week.
The Port Authority of Allegheny County's bus, T and incline service will operate on holiday schedules for Labor Day.
Port Authority's Customer Service phone line will hold holiday hours from 8 a.m. to 4:30 p.m.
