The union representing striking workers at York University says it’s preparing a legal challenge of provincial legislation that would force teachers back to work.

CUPE Ontario president Sid Ryan says the government-backed bill, which is expected to pass Thursday, won’t make the issues at the heart of the strike go away.

He says union lawyers are prepping their case, which can only be launched after the bill is passed.

Premier Dalton McGuinty wouldn’t say whether the government has a plan to deal with the potential roadblock.

Outside the provincial legislature, about 100 students and half-a-dozen parents held a rally calling on the province to get classes resumed quickly.

The spectre of court action didn’t seem to faze the students, many who said they’re confident they’ll be back in class Monday.
