uberxFed up with how they’ve been treated, angry drivers from Uber and UberX are forming an association.

Hundreds of drivers working for the San Francisco-based transportation startup will gather on Sunday just south of Seattle to launch the association. Teamsters Local 117, an organization that helps unions across the Puget Sound region, is supporting the new group that’s designed to “protect drivers’ rights, promote public safety, and raise standards across Seattle’s personal transportation industry.”

In a blog post, Teamsters notes that the drivers made the decision to start an association after meeting on April 13, where addressed concerns about “unjust working conditions,” Uber’s treatment of drivers, and the company’s unwillingness to provide sufficient liability coverage to protect drivers and their customers.

“According to Uber, we’re partners — but they treat us a little better than slaves,” former Uber driver Yedidta Seifu told KING5 last month.

At Sunday’s event, hosted at the Teamsters building in Tukwila, Wash., members of the Western Washington Taxi Cab Operators Association (WWTCOA) — which sued Uber back in March for ‘unlawful and deceptive business practice’ — will be on hand to offer insight into running an organization.

Teamsters rep Paul Zilly told us that drivers from Uber, Lyft and Sidecar are welcome to join the association, which will have a similar model to that of the WWTCOA. Members will vote on Sunday to approve by-laws and elect a leadership council.

Meanwhile in Seattle, Mayor Ed Murray may issue a cease-and-desist letter to UberX, Lyft and Sidecar if an agreement cannot be reached between representatives from the San Francisco-based startups, taxi companies and City officials to create a set of laws for the new startups.
