Parents remember this date: December 10th.That's next Monday and when the province's secondary teachers are planning their next round of strike action.

What was a suggestion before is now mandatory, as Ontario Secondary School Teacher's Federation president Ken Coran says teachers will not be involved in extra curriculars at all. He says union members have been told not to come in more than 15 minutes early and are expected to leave when the final bell rings.

As for field trips, he says only the ones related to school curriculum will go forward.

Coran says this seven-day buffer will give teachers time to explain what's happening to students.

Secondary teachers will also get the opportunity to vote on a day of political protest. However, Coran says they are not considering rotating strike days right now.

He repeated teachers would be willing to accept a two-year wage freeze if Bill 115 - the teacher contract legislation - was repealed.
