Which reason for dismissal allows for remedies related to trade union membership?

The correct answer is related to statutory restrictions associated with trade union membership. Under employment law, particularly regarding collective bargaining and workers' rights, dismissing an employee based solely on their trade union membership or activities is generally regarded as unlawful. This forms part of the statutory protections provided to employees to ensure they can participate in union activities without fear of losing their job.

In many jurisdictions, if an employee is dismissed for reasons connected to their trade union activities, they are often entitled to remedies such as reinstatement or compensation. Such protections are put in place to encourage union membership and collective representation, fostering a balanced negotiation environment between employees and employers.

While misconduct, redundancy, or some other substantial reason can lead to dismissal, these do not inherently provide the same protections or remedies in relation to trade union activities. Therefore, remedies specifically related to trade union membership are grounded in statutory constraints designed to prevent discriminatory practices against unionized employees.
