Workers at a second Better Buzz location in San Diego voted to unionize on Monday. The vote at the Mira Mesa location came almost exactly a month after Better Buzz United announced it had filed the initial paperwork to join the United Food and Commercial Workers (UFCW). Baristas, trainers and shift supervisors at the Mira Mesa store followed the lead of workers at Better Buzz’s location in Hillcrest, who approved unionization in May. Workers at both branches said they have concerns about wages, benefits, scheduling and overall workplace safety.
