article 283 states that:
The employer may also terminate the employment of any employee due to the installation of labor-saving devices, redundancy, retrenchment to prevent losses or the closing or cessation of operation of the establishment or undertaking unless the closing is for the purpose of circumventing the provisions of this title, by serving a written notice on the workers and the Department of Labor and Employment at least one (1) month before the intended date thereof. In case of termination due to the installation of labor-saving devices or redundancy, the worker affected thereby shall be entitled to a separation pay equivalent to at least one (1) month pay or to at least one (1) month pay for every year of service, whichever is higher. In case of retrenchment to prevent losses and in cases of closures or cessation of operations of establishment or undertaking not due to serious business losses or financial reverses, the separation pay shall be equivalent to one (1) month pay or at least one-half (1/2) month pay for every year of service, whichever is higher. A fraction of at least six (6) months shall be considered one (1) whole year.
separation pay is equivalent to 1 month pay OR at least half month salary for every year of service, whichever is higher..
that means.. if you serve your company for only 1 year.. you will get 1 month pay, because that is higher than 1/2 month salary x year of service (which is 1 year only in the example). So the minimum that an employee will get will be 1 month salary. If the number of service is more than 1 year.. then it will be 1/2 month salary x years of service.. because that's higher than 1 month salary.
