Protesters calling for higher wages and union representation for groups including fast-food workers, janitors, and adjunct professors marched through Boston Tuesday afternoon.

A group calling itself the Wage Action Coalition marched from Northeastern University to AMC Loews Boston Common Theater chanting and listening to speeches by labor activists. The march was held one day before rallies affiliated with the “Fight for $15” movement in some 200 other cities because the second anniversary of the Boston Marathon bombing is Wednesday, organizers said.

“We have well over 1,000 folks here with us along the route, and we’re picking up more,” said Veronica Turner, the executive vice president of 1199 SEIU, a union of health care workers. She said about 200 students came out in support of adjunct professors at Northeastern, who voted last year to unionize. She said other organizers told her separate protests held at Boston fast-food restaurants earlier on Tuesday also were well-attended.
