Not as crazy as it sounds:
Though the image of straight-laced hard-working blue-collar labor collaborating with hippy stoners doesn’t quite seem to match up, it is actually a match made in heaven. Labor union memberships have been flagging for some time, and they are in desperate need of a growth industry to latch on to. Meanwhile, marijuana dispensaries have both a branding problem (lacking legitimacy) and a lobbying problem (inability to organize), both of which unions can be of great help.
