The B.C. Labour Relations Board has upheld an employer bid to cut teacher pay by 10% in response to rotating strikes and refusal to perform some duties outside classroom hours.

B.C. Teachers' Federation president Jim Iker said Wednesday the pay cut and partial lockout of members is "a punitive action" that is unfair to teachers performing their essential classroom duties.

In response, the BCTF will hold another vote June 9-10 to authorize full-scale strike action. Rotating strikes are to continue next week while the strike vote is held and counted.

"If approved, this would likely mean a full-scale strike within the next two weeks," Iker said.

the B.C. Teachers' Federation appeal of the partial lockout of teachers in a decision released Wednesday afternoon. He said the two sides are free to seek a third-party resolution of the dispute.

Iker said the union is taking legal advice on the LRB decision and may pursue arbitration.

At the bargaining table, the BCTF has reduced its pay increase proposal by one per cent over four years and offered other concessions in a move to end the stalemate that has led to two weeks of rotating strikes in public schools.

In an email to union members Tuesday night, the BCTF executive said the offer "adjusted the Federation's package in seven areas, including salary, benefits, preparation time and [substitute teacher] compensation."

The new BCTF wage proposal is a total increase of 9.75% over four years, plus cost-of-living adjustments in each year depending on inflation. BCTF president Jim Iker has estimated that with inflation, the total increase would be 12.75% over four years.

The email to teachers describes no response from the B.C. Public School Employers' Association.

BCPSEA, representing the province's 60 school districts, has proposed a 7.5% increase over six years, and recently added a $1,200 signing bonus for an agreement by the end of the school year.

BCPSEA chief negotiator Peter Cameron described the employers' wage proposal as in line with other public sector union agreements already reached.

The two sides remain bitterly divided over class size and special needs support staff, the subject of repeated court actions since those provisions were removed from the teacher contract in 2002.
