If the Union is found guilty the Manitoba Labour Relations Board has the authority to impose a wide range of penalties.

The Labour Board may throw out membership support, dismiss an application for certification, order a secret ballot vote, reinstate employment, pay for lost wages, issue "cease and desist" orders, and post notices of the decision in the workplace.

The Labour Board may order the Union to pay up to $2,000 even if there was no loss of wages; or take other measures to "rectify any situation" resulting from the ULP. Generally, the more serious the breach of the Act, the more serious the penalty.
