In the instant case, PAL admitted that since the pilots strike allegedly created a situation of extreme urgency, it no longer implemented cost-cutting measures and proceeded directly to retrench. This being so, it clearly did not abide by all the requirements under Article 283 of the Labor Code. [The retrenchment] was brought about by and resorted to as an immediate reaction to a pilots strike which, in strict point of law and as herein earlier discussed, may not be considered as a valid reason to retrench, nor may it be used to excuse PAL for its non-observance of the requirements of the law on retrenchment under the Labor Code.
