The Constitution and the Labour Relations Act say that employees have the right to form and join trade unions. This right is called freedom of association. Employers are not allowed to make it a condition of employment that an employee must or must not belong to a trade union. It is the employee’s choice. An employee also cannot be victimised because he or she is a member of a trade union. This means the employer cannot treat the employee unfairly or badly because the employee is a trade union member.
