Nova Scotia's Liberal government is bringing the legislature back early, saying it needs to deal with a potential strike in the health-care sector.

Premier Stephen McNeil's spokesman said the legislature will resume Friday, a month earlier than it was scheduled to begin its next session.

Kyley Harris said Wednesday that McNeil requested the session to deal with a pending strike by 420 home-support workers in the Halifax area.

He wouldn't give specific details, but he said the government is considering its legislative options to deal with the labour issue.

The workers, who are represented by the Nova Scotia Government and General Employees Union, are set to walk off the job at midnight Friday.

The union says the workers last contract expired in March 2012 with home-support provider Northwood and they are looking for contract parity with those doing the same work in hospitals.

The Liberals have a majority in the legislature.

Progressive Conservative Leader Jamie Baillie issued a statement Wednesday calling on McNeil to act on the looming strike by bringing back the legislature.

"As the home-support workers edge closer to their strike, families are increasingly worried about their loved ones," Baillie said.
