Women’s History Month, a national observance, is held every March.
Evelyn Brown began delivering mail in Washington, DC, in 1963, becoming the first woman to deliver mail in a city since the World War II era
“Women play a critical role in America’s workforce,” said Postmaster General Megan J. Brennan. “This is especially true in the Postal Service, where women have been a part of postal operations from the beginning. We are proud to celebrate the historic role of women in our organization, and we look forward to their continued contributions in the future.”
Throughout the Postal Service’s history, women have led advancements in all areas — including mail processing and delivery, transportation, management and other functions.
Today, the USPS workforce includes about 289,500 women, or more than 45 percent of employees.
