The Hyatt Regency Cambridge at 575 Memorial Drive, Cambridge, has been targeted for a picket Sunday over employment practices.

The Boston Workmen’s Circle plans a picket Sunday in honor of the Hyatt 100, the Cambridge and Boston hotel housekeepers fired Aug. 31 when their employer decided to outsource the work to save money.

“Exciting news,” program and membership organizer Leah Madsen said Tuesday in an e-mail to the group of secular, progressive Jews, whose activities tend to be loud, fun and in the spirit of social justice. “Instead of gathering at the Workmen’s Circle this Sunday, we’re heading over to support the Hyatt 100! At a picket in Cambridge – Join us!”

“Will we let Hyatt off the hook?” Madsen asked. “NO WAY!”

After the picket, which goes from 11:30 a.m. to 1 p.m. at the 575 Memorial Drive, Cambridge, hotel, a picnic is planned for along the Charles. People are urged to bring sandwich fixings and other food to share, as well as blankets and Frisbees.

Here are previous posts about the Hyatt 100, mostly lower-income women who devoted decades to careful housecleaning and, when the Chicago-based chain was under pressure from intense negative publicity, were offered their old jobs back —through agencies that would pay them half what they’d been earning.

And here’s the tale of the circle:

In 1892, a group of cloakmakers gathered in a tenement on New York’s Lower East Side and formed a mutual aid society formally chartered in 1900 as the Workmen’s Circle/Arbeter Ring. Through skillshares, political action, and more, we keep this spirit of communal support and camaraderie alive today. Join us!
