Normal ER visits are those that bring themselves in. Trauma patients are the ones coming in via 911 calls, ambulances, helicopters, etc. General rule of thumb-they are obvious exceptions as stabbings & gunshot wounds do happen outside of hospitals or the victims come wandering in.
Labor Day is a United States federal holiday which is observed on the first Monday in September each year. The holiday originated on September 5, 1882 as the Central Labor Union of New York City sought to create a day off work for the working citizens.
Labor Day is always observed on the first Monday of September. This means that it is connected with the weekend before it, creating a three day weekend for most people who are employed on a regular Monday through Friday work week. Also, since it is in September, Labor Day usually marks the end of summer time.
