Unfortunately, the legalization of medical marijuana may be causing problems for those working at medical marijuana dispensaries.

The workers who care for and sell cannabis strains at the Compassionate Care Foundation facility are reportedly preparing for a hearing before the National Labor Relations Board after a majority stated that their attempt to join a union was blocked by their employer, according to the website Philly.com.

The employees reportedly filed unfair labor practice charges after their attempt to unionize led to lower wages and a change in hours, according to The Associated Press.

The employees reportedly took a voluntary “temporary 60-day pay cut” in July when Compassionate Care said it was having financial difficulties.

Despite the employer saying that their pay would be reinstated at the end of October, their salaries were not restored.

Brian String, the president of Local 152, reportedly told The Philadelphia Inquirer that the medical marijuana dispensary was using “tricks from the usual anti-union playbook,” including reclassifying employees as agricultural workers.

The National Labor Relations Board is reportedly scheduled to hear the case on March 16 in Philadelphia, according to NLRB spokesperson Jessica Kahanek. The complaint reportedly surfaced after CEO and president Bill Thomas abruptly resigned.

Thomas had reportedly publicly spoken against the state’s marijuana regulations, calling them “onerous” and stating that they interfered with sound business practices.

Mark Belland, a Cherry Hill lawyer who represents Local 152 has reportedly stated that Compassionate Care “informally suggested” that it might question whether the National Labor Relations Board can hear the case as the federal government’s view remains that marijuana is illegal.

New Jersey is reportedly one of the 23 states that have legalized marijuana.
