The Province of Manitoba has made a move to prevent a group of health workers from striking.

Workers at Canadian Blood Services in Winnipeg were expected to walk picket lines on Friday, but the province stepped in just a day ahead of the anticipated strike and declared CBS an essential service.

Workers who provide essential services are not allowed to strike under Manitoba legislation.

Earlier this year, CBS workers turned down a tentative settlement on a new contract with their employer.

It was the second tentative deal rejected by the employees since January.

CBS employs 107 people in Winnipeg and another 13 in Brandon.
