Everyone who calls a cubicle their second home or knows how to work the office coffee machine better than their own knows that office managers are the backbone of most workplace environments.

Administrative Professionals Day is a day to acknowledge and give thanks for the efforts of your administrative assistant, receptionist office manager or other vaulable admin person. The unofficial holiday, which falls on April 23 this year, is the time to show how much you appreciate everything they do.

The day was established in 1952. At the time, it was called "National Secretaries Week" and organized by the National Secretaries Association, which is now known as the International Association of Administrative Professionals.

The idea came from Mary Barrett, then president of the National Secretaries Association, and C. King Woodbridge, then president of Dictaphone Corp. The day was meant to recognize secretaries’ contributions to the workplace and attract new skilled office workers.

In addition to gifts for the administrative assistants in your office, here are 15 quotes to share on Administrative Professionals Day.
