PART II LABOUR RIGHTS AND PRACTICES — Coercion and persuasion
28
(1) An employee, or person acting on behalf of a trade union, shall not use coercion or intimidation with a view to encourage or discourage membership in or activity in or for a trade union, but nothing in this Act precludes a person acting on behalf of a trade union from attempting to persuade an employer to make an agreement with that trade union requiring, as a condition of employment with that employer, membership or maintenance of membership in that union or other condition with regard to employment, where the union has been designated or selected by a majority of employees in the unit concerned as their bargaining agent.
28(2)
Except with the consent of the employer, but subject to an order made by the board under section 34, a trade union and a person acting on behalf of a trade union shall not attempt, at an employer's place of employment during the working hours of an employee of the employer, to persuade the employee to become or refrain from becoming or continuing to be a member of a trade union.
