During World War II, there was a shortage of skilled administrative personnel in the United States due to the depression-era birth rate decline. That combined with the booming post-war business, created a skilled office-workers shortage. The National Secretaries Association, founded in 1942, was formed to recognize the contributions of administrative personnel to the economy, support their personal development, and help attract workers to the administrative field. Key figures who created the holiday were the president of the National Secretaries Association, Mary Barrett; president of Dictaphone Corporation, C. King Woodbridge; and public relations account executives at Young & Rubicam, Harry F. Klemfuss and Daren Ball.

The National Secretaries Association‘s name was changed to Professional Secretaries International in 1981 and to the International Association of Administrative Professionals (IAAP) in 1998. Administrative Professionals Day is a registered trademark with registration number 2475334 (serial number 75/898930). The registrant is IAAP.

The official period of celebration was first proclaimed by U.S. Secretary of Commerce Charles W. Sawyer as “National Secretaries Week”, which was held June 1–7 in 1952 with Wednesday, June 4 designated as National Secretaries’ Day. The first Secretaries’ Day was sponsored by the National Secretaries Association with the support of corporate groups.

In 1955, the observance date of National Secretaries Week was moved to the last full week of April, with Wednesday now designated as Administrative Professionals Day. The name was changed to Professional Secretaries Week in 1981 and became Administrative Professionals Week in 2000 to encompass the expanding responsibilities and wide-ranging job titles of administrative support staff in the modern economy. The week-long observance was created in order to space out the bookings at restaurants, country clubs, and other places where administrative professionals would be taken out to lunch.
