A collective agreement binds-
the parties to the collective agreement;
each party to the collective agreement and the members of every other party to the collective agreement, in so far as the provisions are applicable between them;
terms and conditions of employment; or
the conduct of the employers in relation to their employees or the conduct of the employees in relation to their employers;
the employees are identified in the agreement;
the agreement expressly binds the employees; and
A collective agreement binds for the whole period of the collective agreement every person bound in terms of subsection (1)(c) who was a member at the time it became binding, or who becomes a member after it became binding, whether or not that person continues to be a member of the registered trade union or registered employers' organisation for the duration of the collective agreement.
Where applicable, a collective agreement varies any contract of employment between an employee and employer who are both bound by the collective agreement.
Unless the collective agreement provides otherwise, any party to a collective agreement that is concluded for an indefinite period may terminate the agreement by giving reasonable notice to the other parties.
