The class size clause was indeed bargained. Not liking it now is irrelevant. As with all bargaining, it is a question of give and take; the BC Liberals did nothing but take - they took away contract clauses illegally and offered sub-inflation or no raises at all for years on end to the point that BC teachers are at the bottom-end nationally for salary. Perhaps if the Liberals had offered the prospect of a decent raise, teachers may have been flexible on class size clauses, but given the illegal treatment by the Liberals and poor wage offers, teachers had little reason to display flexibility.
