Starbucks sued again over tip pools. (Seattle Times)

A week after Starbucks was ordered to refund more than $100 million to baristas in California over a tip pool controversy, the coffee giant was hit Tuesday with a similar lawsuit in Massachusetts.

And a Boston lawyer said more lawsuits could be filed in Washington, New York and Minnesota over whether shift supervisors can share baristas’ tips.

In Suffolk Superior Court, barista Hernan Matamoros seeks restitution for himself and other baristas who worked for Starbucks during the past six years. He claims baristas did not receive the “total proceeds of tips” left by customers because the company allowed shift supervisors to have a portion of them.

Shannon Liss-Riordan, an attorney who filed the suit, said Massachusetts’ law is even clearer than California’s law that “anyone with managerial authority is not an employee who may receive a share of tips.”
