BOSTON - Hotel workers went on strike in Boston Thursday morning for a third time this month. This time, workers at the Omni Parker House, Omni Boston Seaport, Renaissance Boston Seaport, and Westin Boston Seaport walked off the job at 7 a.

"We're showing them that we got to do what we got to do to get our raise," Renaissance Seaport hotel worker Dee Dee Jones said from their picket line Thursday morning. "Nobody wants to strike. It's sad that we had to strike just to get a new contract.

It's the third wave of hotel worker strikes in Boston since Sept. 1, when workers at four hotels took to the picket lines over Labor Day weekend. Last week, 450 workers went on strike for three days at four more hotels in Boston. Thursday's strike is the biggest one in Boston so far, with 1,200 workers at four hotels participating.
