The Pima Area Labor Federation, a subsidiary of the Arizona AFL-CIO, will host its annual Labor day picnic Monday in Tucson.

The event is open to the public at no charge, and will feature musical acts, dancers, labor history exhibits, children's activities and “Union Olympics” games.

Hot dogs will be served at the picnic, which runs from 10 a.m. to 2 p.m. Monday at the Reid Park Bandshell, in the area of Country Club Road and 22nd Street.
