My employer recently gave me an employment agreement to sign which says that either party may terminate the agreement by giving one months written notice to the other.

Does this mean that my employer can terminate my employment without cause by simply giving me one months notice in writing?

If my employer were to give me notice, would this be a dismissal?

A dismissal is a termination of employment at the initiative of the employer.

Accordingly, if your employer was to give you notice of termination, it would be a dismissal because your employer is responsible for your employment coming to an end.

The Employment Relations Act prohibits employers from dismissing employees unjustifiably.

This means that your employer must have a justifiable reason for dismissing you such as serious misconduct, poor performance, or redundancy.

Your employer cannot end your employment without justification by simply giving you one months written notice of termination.
