Philadelphia's largest municipal employee union, District Council 33, has voted to authorize a strike against the city.

Philadelphia’s largest union representing city workers officially authorized its members to go on strike if their demands for better wages are not met.

The results announced Thursday showed 87% of workers voted in favor of the strike authorization. This does not mean workers are hitting the picket line, however. DC 33 says the vote simply gives union leaders the authority to call a strike at any time.

A union representing thousands of city employees, including sanitation workers, has voted to authorize a strike. This doesn't mean they're on strike yet but it allows union leadership to call one if necessary at any time.
