The labor union representing more than 200 Minneapolis Park and Recreation Board employees voted to authorize a strike this week.

LIUNA Local 363 employees cast ballots with 94% in favor, the union said in a Facebook post.

Employees have for years called for improvements to wages, health care and safety precautions, AJ Lange, Business Manager of LIUNA Local 363 said in a statement.

“Despite our endless hard work, skill, and dedication that makes Minneapolis’ parks the best in the nation, management continues to treat us with contempt,” Lange said.
