Members of AFSCME District Council 33, the union representing blue-collar workers for the city of Philadelphia, will begin to vote on their new contract agreement starting Monday.

District Council 33 President Greg Boulware wouldn't recommend that union members vote in favor of or against the tentative agreement made with the Parker administration.

The contract, if ratified by DC 33's membership, is retroactive to July 1. After more than a week on strike and several stalled negotiation sessions, leaders of Philadelphia’s largest municipal union came to an agreement with the city this week, returning roughly 9,000 workers to the job.
