The union representing more than 200,000 public transit workers in the U.S. and Canada said its members in Minneapolis have the right to refuse to transport police, in solidarity with protests over the police killing of George Floyd.

“As our members – bus drivers – have the right to refuse work they consider dangerous or unsafe during the pandemic, so too Minneapolis bus drivers – our members – have the right to refuse the dangerous duty of transporting police to protests and arrested demonstrators away from these communities where many of these drivers live,” union President John Costa said in a statement Thursday.

ATU Local 1005, the union’s chapter in Minneapolis and St. Paul, issued a letter of solidarity with the protesters, calling for “a new Civil Rights Movement ... that is joined with the labor movement.”

A spokesperson would not say if the suspension was solely due to the protests, the Minneapolis Star Tribune reported.

It’s also unclear if the decision was directly related to the transit workers’ solidarity action.
