The Footlight Club's newest production Sweat tells the story of a group of friends who have spent their lives toiling together in a factory. Opening this weekend, the play written by Lynn Nottage, is full of warm humor and tremendous heart. As coworkers do, they became friends by enjoying drinks together, sharing secrets and laughs. "But when layoffs and picket lines begin to chip away at their trust, the friends find themselves pitted against each other in a heart-wrenching fight to stay afloat," describes The Footlight Club's website. Sweat opens on Saturday, Feb.
