VANCOUVER - British Columbia's 40,000 public school teachers have voted to accept a new contact, bringing an end to a year-long labour dispute that saw teachers reduce service and shut down classes during a brief walkout.

The B.C. Teachers' Federation announced Friday night that its members voted 75 per cent in favour of the tentative agreement that was reached earlier in the week. Turnout was low, at 52 per cent.

The contract includes improved benefits and seniority provisions but no wage increases. The employers' association bargained under a provincial government policy that said any wage increases must be offset by concessions elsewhere in the contract.

The dispute has overshadowed the entire school year, with teachers refusing to perform certain administrative tasks such as filling out report cards and, in March, staging a three-day walkout.

The Yes vote means those disruptions won't affect students when classes resume from summer break in the fall, but that stability may be short lived. The new contract ends in June of next year, just a month after a provincial election, promising to set off a fresh round of what will almost certainly be heated negotiations.

The B.C. Teachers' Federation recommended teachers vote in favour of the contract, but the union complained it only agreed to the deal because the province would have otherwise legislated a new contract.

The union also launched a fresh court challenge alleging the province violated teachers' right to collective bargaining when it introduced back-to-work legislation earlier this year.

The dispute largely focused on wages, with teachers initially asking for a 15 per cent pay increase, although there were other issues such as class size and composition.

Teachers overwhelmingly voted to strike last year to back their demands, but because of essential-services legislation, they aren't allowed to stage any job action, including a full-scale walkout, without the approval of the province's Labour Relations Board.

The teachers started the school year refusing to perform certain administrative tasks.

That continued until February, when the province revealed it was considering legislation to force the teachers to return to their normal duties. The same week, a government-appointed fact finder released a report that concluded there was little hope the two sides would reach a deal through negotiations.

The prospect of back-to-work legislation prompted teachers to return to the labour board to ask for permission to walk off the job. The board ruled teachers could walk out of classes for three days, which they did in March.

Shortly after, the legislature passed its controversial back-to-work legislation, which prevented teachers from walking off the job or staging any further job action, imposed a so-called cooling off period and appointed a mediator to broker a deal. The legislation, Bill 22, required any new deal to comply with the province's no-wage-increase policy.

In the meantime, the teachers also asked the B.C. Supreme Court to order a new mediator be appointed. The union argued the mediator, Charles Jago, was biased and didn't have the qualifications necessary to fill the post.

While that court case may be of little consequence now that teachers have voted to accept the tentative agreement, the B.C. Supreme Court nonetheless released its ruling on Friday, rejecting the teachers' case and upholding Jago's appointment.

Education Minister George Abbott was free to exercise his discretion in appointing a mediator, and Jago's appointment was reasonable, Judge Hope Hyslop wrote in a decision posted to the court's website.

While that legal challenge is out of the way, the teachers launched another one this week.

A petition filed in B.C. Supreme Court on Wednesday argues the back-to-work law passed by the legislature earlier this year violates teachers' charter rights to collective bargaining.

The union's notice of claim says the law put too many restrictions on the mediator and again complains about Jago's impartiality.

It also says the province has ignored a court decision from last year that struck down legislation preventing teachers from including class size and composition in collective bargaining.
