(Fox News) — Staffers at the White House budget office filed a petition Monday to join a labor union, seeking to gain more input over their working conditions.

About half of the career work force at the Office of Management and Budget signed the petition, said Peter Winch, deputy director of field services and education for the American Federation of Government Workers.

Winch said the move is not a signal that workers are unhappy at the agency, but a sign that they would like more of a voice in how the office is organized and more appreciation for the work they do.

“A lot of people are expected to come in on weekends and work late,” Winch said. “They don’t mind that culture, because they feel they are engaged in very important work, but they would like more recognition for the fact that they do make those sacrifices.”

The office, which helps the president prepare the federal budget, has been reorganized over the past year. Winch said some workers would have wanted their point of view considered when those changes were made.

AFGE [part of the AFL-CIO -ed.] is the nation’s largest federal employee union, representing about 600,000 workers in the federal government and Washington, D.C.

Now we know why AFL-CIO chief Richard Trumka “visits the White House 4 to 5 times a week and talks to them everyday.”
