Reuters:  “The medical marijuana shop next to a tattoo parlor on a busy street in Los Angeles looks much like hundreds of other pot dispensaries that dot the city.  Except for one thing: On the glass door – under a green cross signaling that cannabis can be bought there for medical purposes – is a sticker for the United Food and Commercial Workers union (UFCW), the nation’s largest retail union.  The dispensary, the Venice Beach Care Center, is one of three medical marijuana dispensaries in Los Angeles that are staffed by dues-paying union members. Another 49 in the city plan to enter into labor agreements with the UFCW this year, the union says.”
