Collective bargaining - Good faith

33: Duty of good faith requires parties to conclude collective agreement unless genuine reason not to

You could also call this:

“Be fair and try to agree when making a workplace deal, unless you have a really good reason not to.”

When you are bargaining for a collective agreement, you and the other party must try to reach an agreement. You must do this in good faith, as stated in section 4. This means you should conclude a collective agreement unless there is a genuine reason not to.

A genuine reason does not include opposing a collective agreement because you do not like the idea of one. It also does not include disagreeing about including a bargaining fee clause under Part 6B in a collective agreement. It does not include the existence of an unsettled pay equity claim between an employer and a claimant under the Equal Pay Act 1972.

If you do not want to conclude a multi-employer collective agreement, that can be a genuine reason if you have reasonable grounds for opposing it. A multi-employer collective agreement is a single collective agreement involving two or more employers. However, clause 6 of Schedule 1B overrides this rule.
