The employees went on strike for one day in February. SEIU Local 26 President Iris Altamirano says this is the best agreement they’ve ever negotiated.

“It is a … significant raise just this year, which is why we need the vote to occur,” Altamirano said. “It’s a $2.20 raise over the next four years.”
