Unhappy Hastings hospital workers with contract offers from management walked picket lines and rallied outside Regina Medical Center in Hastings.
The workers alleged on Monday, saying they already struggle to pay their bills. Union members have been without a contract since Oct. 31.
Union workers say the costs they would bear under the new proposal exceed the pay increase.
Meanwhile, the union called for a two-day strike to take a stand for working families, said Ryan Nagle, a union spokesman.
About 230 union members of Service Employees International Union (SEIU) Healthcare Minnesota started their two-day strike at 6 a.m. after failing to resolve differences with hospital management over pension contributions and health insurance costs.
