1. An employer cannot unilaterally alter the terms of an employment in relation to pay or hours worked without the consent of the employee. Nor can any matters relating to pension rights be altered without the consent of the employee. However, an employer can alter the non-essential terms of the employment contract upon notice to the employee. Accordingly, the answer to your question is that an employer cannot alter pay or hours worked without the consent of the employee but the employer can alter non essential terms upon notice to the employee. If you wish to provide further details on how your employment contract is being altered, I will help further. Be aware that if your pay or hours worked has been unilaterally altered, you can make a complaint to a Rights Commissioner to have the terms re-imposed. Negotiations can then take place to see if negotiation between the employer and employee can lead to a resolution. However, the terms of the employment contract will remain the same unless the employee consents to change.
