Tens of thousands of Quebec post-secondary students are now on strike against tuition-fee hikes.

About 31,000 students from colleges and universities have deserted their classrooms since Friday as part of an increasingly active campaign against the Charest government.

The strikes are the result of votes, with students in some universities and colleges choosing to use the tactic to apply pressure on the government.

While less than 10 per cent of all students have chosen to participate, the figure is expected to grow slightly tomorrow with a few thousand more from another college joining their ranks.

They're upset that the government will nearly double tuition, to $3,800 from the current $2,200, over five years. They say education is a fundamental right and the tuition increase will discourage some people from continuing their studies.

But the government notes that Quebec tuition is so low that, even with the increase, it will still be the lowest in Canada.
