The idea began with Mary Barrett, president of the National Secretaries Association, now called IAAP, and C. King Woodbridge, president of Dictaphone Corporation. They served on a council addressing a national shortage of skilled office workers. Together with Harry Klemfuss, public relations account executive at Young & Rubicam, they originated the idea for a National Secretaries Week. 
Office workers have been honored by the International Association of Administrative Professionals by sponsoring Administrative Professionals week since 1952.
In the year 2000, IAAP announced a name change for Professional Secretaries Week and Professional Secretaries Day. The names were changed to Administrative Professionals Week and Administrative Professionals Day to keep pace with changing job titles and expanding responsibilities of today’s administrative workforce.
Administrative Professionals Week is one of the largest workplace observances. Celebrated worldwide it brings together millions of people for community events, educational seminars and individual corporate activities recognizing support staff.
There are more than 4.1 million secretaries and administrative assistants working in the United States and 8.9 million people working in administrative support roles. Millions more administrative professionals work in offices all over the world.
Administrative Professionals Week is April 22-28, and Administrative Professionals Day is Wednesday, April 25.
