DORCHESTER, MA - APRIL 18:  Former Vice President Joe Biden speaks in front of a Stop & Shop in support of union workers on April 18, 2019 in Dorchester, Massachusetts. Thousands of unionized Stop & Shop workers across New England walked off the job last week in an ongoing strike in response to a proposed contract which the United Food & Commercial Workers union says would cut health care benefits and pensions for employees.
