Sira Naturals is a company that specializes in the production and sale of cannabis in Massachusetts. Recently, workers at Sira Naturals have voted to unionize. 115 employees of Sira Naturals voted to join Local 1445 of the United Food and Commercial Workers Union (UFCW). As legislation continually changes around cannabis, there are signs of a growing trend of unionization in the industry.
