Drivers supportive of the bill, organized by the Massachusetts Coalition for Independent Work, also submitted written testimony. More than 3,200 drivers signed the letter.

“Opponents will tell you they know what’s best for drivers, but we know what’s best for ourselves,” they wrote. “We want to remain independent. If drivers are reclassified as employees, most of us will be unable to do this work. Some of us already have full-time jobs. For others, the rigidity that comes with employment will simply not work alongside family obligations.”
