The union representing Ontario's public high school teachers says it's suspended all talks with school boards until
further notice.

The Ontario Secondary School Teachers' Federation says it's making the move because the government refused to give approval to a number of locally bargained deals.

The union says the Ministry of Education decided the tentative agreements weren't ``substantively identical'' to a deal the
province signed with English Catholic teachers this summer.

That agreement froze the wages of most teachers and cut benefits, such as stopping the banking of sick days to be cashed out at retirement.

The union says it's also due to the rejection of tentative agreements by teachers in York Region and Niagara earlier this week.

It says the ratification vote of an agreement reached at Hamilton-Wentworth School Board will proceed on Friday, but all
other scheduled votes have been put off until after Monday.
