Employees may terminate their employment. And, unlike employers, they may do so even without just cause. All they need to do is simply serve a written notice on their employers at least one month in advance.
But employees who desire to terminate their employment must comply with the required one-month advance written notice, because, otherwise, they may be held liable for damages.
Employees may, nevertheless, terminate their employment even without serving any notice on their employers for any of the following just causes:
1. Serious insult by the employer or his representative on the honor and person of the employee;
2. Inhuman and unbearable treatment accorded the employee by the employer or his representative;
3. Commission of a crime or offense by the employer or his representative against the person of the employee or any of the immediate members of his family; and,
4. Other causes analogous to any of the foregoing.
Employees who terminated their employment without serving any notice on their employers for any of these just causes may not be held liable for damages.
