"To be precise, closure or cessation of an employer’s business operations, whether in whole or in part, is governed by Article 283 of the Labor Code, as amended. It states:
Article 283.Closure of establishment and reduction of personnel. - 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 Ministry 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 his 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.26
In Industrial Timber Corporation v. Ababon,27 the Court explained the above-quoted provision in this wise:
A reading of the foregoing law shows that a partial or total closure or cessation of operations of establishment or undertaking may either be due to serious business losses or financial reverses or otherwise. Under the first kind, the employer must sufficiently and convincingly prove its allegation of substantial losses,while under the second kind, the employer can lawfully close shop anytime as long as cessation of or withdrawal from business operations was bona fide in character and not impelled by a motive to defeat or circumvent the tenurial rights of employees, and as long as he pays his employees their termination pay in the amount corresponding to their length of service. Just as no law forces anyone to go into business, no law can compel anybody to continue the same. It would
be stretching the intent and spirit of the law if a court interferes with management's prerogative to close or cease its business operations just because the business is not suffering from any loss or because of the desire to provide the workers continued employment.
In sum, under Article 283 of the Labor Code, three requirements are necessary for a valid cessation of business operations: (a) service of a written notice to the employees and to the DOLE at least one month before the intended date thereof; (b) the cessation of business must be bona fide in character; and (c) payment to the employees of termination pay amounting to one month pay or at least one-half month pay for every year of service, whichever is higher.28
