The new marijuana laws in Minnesota are causing headaches for employers.

Take Paul Blom, who deals with the complexity of them as a member of his North Loop condo board and as chief executive of a home health care agency.

The state joins 22 others on Aug. 1 when it decriminalizes the recreational use of cannabis.

The shift is emboldening people to smoke marijuana in new places — even if not permissible under Minnesota’s new law, Blom said.

At his condominium complex, he had to remind neighbors their smoke shouldn’t infiltrate the common corridors.

In the workplace, a person’s job determines whether they can be tested for THC before or during employment. For instance, Blom’s employees can be tested because they are health care workers. It is also legal for any employer to have policies that limit the use of cannabis on-site.

Minnesota employment attorneys, human resource professionals and chambers of commerce all say they are getting bombarded with questions and are coaching employers to batten down work rules before the new law takes effect.

“You definitely have to have a policy for something like this,” said Blom, CEO of Right at Home in Bloomington.
