Separation pay in the Philippines is not automatic. Whether you receive it, and how much, depends entirely on why the employment ended.
Just cause versus authorised cause
Dismissal for just cause — serious misconduct, wilful disobedience, gross neglect, fraud, and similar — generally carries no separation pay.
Termination for authorised cause — redundancy, retrenchment, installation of labour-saving devices, closure, or disease — does carry separation pay.
The rates differ by cause
The Labor Code sets different multipliers depending on which authorised cause applies. Redundancy and the installation of labour-saving devices are treated differently from retrenchment and closure.
Confirm which ground your employer invoked, because it determines the rate.
The procedural chain
Dismissal requires just cause or authorised cause plus the full procedural chain. Skipping the process is itself a violation, even where the underlying reason is valid.
