List and briefly discuss the common -law grounds for terminating a contract of employment and explain what each ground entail?

1. Breach of contract: This occurs when one party fails to fulfill their obligations as outlined in the employment contract. This could include not showing up for work, not performing duties as required, or violating company policies.

2. Frustration of purpose: This occurs when unforeseen circumstances make it impossible for the contract to be fulfilled. For example, if an employee becomes permanently disabled and is unable to perform their job duties, the contract may be frustrated.

3. Mutual agreement: Both parties may agree to terminate the contract for various reasons, such as a change in business needs or personal circumstances.

4. Constructive dismissal: This occurs when an employer makes significant changes to the terms of employment without the employee's consent, leading to a breach of the employment contract. This could include reducing pay, changing job duties, or creating a hostile work environment.

5. Repudiatory breach: This occurs when one party indicates that they no longer intend to fulfill their obligations under the contract. This could include an employer refusing to pay wages or an employee refusing to work.

Each of these grounds for terminating a contract of employment involves a breach or change in the terms of the agreement, leading to the need for termination. It is important for both parties to understand their rights and obligations under the contract to avoid disputes and potential legal action.
