AFSCME District Council 33, which has over 9,000 members in sanitation, water department, prisons and more, could call a strike as they seek better pay.

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.

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.

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