Interphil Laboratories Employees Union-FFW vs. Interphil Laboratories, Inc.

The Secretary of Labor and Employment has jurisdiction under Article 263(g) of the Labor Code over cases pending before Labor Arbiters when the issues are intertwined with the assumed labor dispute; an "overtime boycott" (concerted refusal to render overtime work) and "work slowdown" constitute an illegal strike, particularly when violating a contractual no-strike clause; and the parol evidence rule does not apply in a rigid and technical sense in labor proceedings before the NLRC or Labor Arbiters.

The case involves a labor dispute between Interphil Laboratories, Inc., a pharmaceutical manufacturer operating on a continuous 24-hour production schedule, and its rank-and-file employees represented by Interphil Laboratories Employees Union-FFW. The dispute arose during the renegotiation of their CBA, which was set to expire on July 31, 1993. While the CBA provided for eight-hour workdays from 7:30 a.m. to 4:30 p.m., the company had been operating on a twelve-hour two-shift schedule (6:00 a.m. to 6:00 p.m. and 6:00 p.m. to 6:00 a.m.) since 1988, which employees followed and for which they received overtime pay. The union employed concerted work stoppage tactics to pressure the company into agreeing to specific terms regarding the duration and effectivity of the new CBA.

• Interphil Laboratories, Inc. is engaged in manufacturing and packaging pharmaceutical products requiring continuous 24-hour operations.
• Interphil Laboratories Employees Union-FFW is the sole and exclusive bargaining agent of the rank-and-file employees.
• The parties had a CBA effective from August 1, 1990 to July 31, 1993, which provided in Article VI, Section 1 that regular working hours were from 7:30 a.m. to 4:30 p.m. (eight hours), but allowed the company to change prevailing work time at its discretion and required employees to observe company rules regarding working hours.
• Since 1988, the company had been operating on a two-shift schedule of 6:00 a.m. to 6:00 p.m. and 6:00 p.m. to 6:00 a.m. (twelve hours each), which employees followed without question or complaint and for which they received overtime pay.
• In February and March 1993, union officers approached the company Vice-President for Human Resources regarding the duration of the new CBA and were informed the matter would be discussed during formal renegotiations.
• On April 15, 1993, union officers demanded that the new CBA be effective August 1, 1993 for a duration of two years; the company declined to decide, stating it was premature.
• On April 16, 1993, all rank-and-file employees refused to follow the twelve-hour shift schedule, stopping work at 2:00 p.m. and 2:00 a.m. (after eight hours) without sealing containers or securing raw materials, and told management to "ask the union officers."
• Union Director Enrico Gonzales informed management that employees would return to the twelve-hour schedule only if the company agreed to their CBA demands regarding duration and effectivity.
• The employees engaged in a work slowdown campaign during working hours, causing production delays and client complaints.
• The overtime boycott and work slowdown continued from April 16, 1993 until March 7, 1994.
• The CBA contained a provision prohibiting the union or any employee from staging a strike or engaging in slowdown or interruption of work during the existence of the CBA.
• Testimonial evidence established that the union officers instigated the overtime boycott, with one union officer instructing employees to "invent various excuses" to avoid overtime work and referring to the coordinated action as "showtime."

• The Court of Appeals committed grave abuse of discretion in disregarding the "parol evidence rule" by admitting evidence regarding the twelve-hour shift schedule contrary to the CBA provision stating regular working hours were only from 7:30 a.m. to 4:30 p.m., arguing that the written CBA should control and preclude extrinsic evidence of actual practice.
• The Court of Appeals committed grave abuse of discretion in not declaring the company's extension of substantial separation packages to union officers during the pendency of the case as tantamount to condonation of any alleged illegal acts.
• The Court of Appeals committed grave abuse of discretion in holding that the Secretary of Labor has jurisdiction over a case (petition to declare strike illegal) which had long been filed and pending before the Labor Arbiter, arguing that the Labor Arbiter had exclusive original jurisdiction over illegal strike cases under Article 217 of the Labor Code.

• The Secretary of Labor has authority under Article 263(g) of the Labor Code to assume jurisdiction over the entire labor dispute, including intertwined cases pending before Labor Arbiters, to prevent conflicting rulings and ensure effective resolution.
• The parol evidence rule does not apply in a rigid and technical sense in labor cases before the NLRC or Labor Arbiters, and the CBA itself allowed the company to change work schedules at its discretion; moreover, employees had waived the eight-hour schedule by accepting the twelve-hour arrangement since 1988.
• The "overtime boycott" and "work slowdown" constituted an illegal strike, violating the CBA's express prohibition against strikes, slowdowns, or interruptions of work during the CBA's existence, and amounted to a "strike on the installment plan" designed to coerce management.
• The separation packages granted to union officers did not constitute condonation but were acts of generosity or compliance with legal obligations while the officers were still considered employees, and the company could have withheld these benefits pending final resolution.

• Procedural:
  • Whether the Secretary of Labor and Employment has jurisdiction over a case already pending before a Labor Arbiter when the Secretary assumes jurisdiction over the related labor dispute under Article 263(g) of the Labor Code.
  • Whether the parol evidence rule applies to prevent the admission of evidence regarding work schedules contrary to the written provisions of the CBA in labor proceedings.
• Substantive Issues:
  • Whether the concerted "overtime boycott" (refusal to work beyond eight hours contrary to established twelve-hour practice) and "work slowdown" constitute an illegal strike under the Labor Code and in violation of the CBA.
  • Whether the grant of separation packages by the company to union officers during the pendency of the case constitutes condonation of the alleged illegal acts.

• Procedural:
  • The Secretary of Labor has jurisdiction over cases pending before Labor Arbiters when such cases are intertwined with the labor dispute subject of the assumption order under Article 263(g) of the Labor Code. The authority to assume jurisdiction extends to all questions and controversies arising therefrom, including cases over which the labor arbiter has exclusive jurisdiction, to prevent absurd results of conflicting rulings and to ensure effective disposal of the primary dispute.
  • The parol evidence rule does not apply in a rigid and technical sense in labor cases pending before the NLRC or Labor Arbiters. The rules of evidence prevailing in courts of law or equity are not controlling in labor cases, and the Labor Arbiter is not precluded from accepting and evaluating evidence other than, or even contrary to, what is stated in the CBA.
• Substantive:
  • The "overtime boycott" and "work slowdown" constitute an illegal strike. The concerted refusal to adhere to the established twelve-hour work schedule, practiced since 1988 with the employees' acquiescence and acceptance of overtime pay, was designed to coerce the company into acceding to union demands during CBA negotiations. Such acts violate the CBA's express prohibition against staging strikes or engaging in slowdowns or interruptions of work during the CBA's existence.
  • The acts amount to a "strike on the installment plan" or slowdown, which is inherently illegal as it involves a willful reduction in the rate of work by concerted action to restrict output and compel management to grant demands, even while employees continue to work and accept wages.
  • The grant of separation packages does not constitute condonation. The company granted these benefits while the officers were still considered employees, constituting either compliance with legal obligations or an act of generosity due to financial hardships and economic conditions, for which the company should not be punished.

• Assumption of Jurisdiction under Article 263(g) of the Labor Code — The Secretary of Labor's authority to assume jurisdiction over labor disputes causing or likely to cause strikes in industries indispensable to the national interest extends to all questions and controversies arising therefrom, including cases over which Labor Arbiters have exclusive jurisdiction, to ensure effective and efficient resolution of the primary dispute and avoid conflicting rulings.
• Parol Evidence Rule in Labor Proceedings — The parol evidence rule, which bars evidence of terms other than those in a written agreement, does not apply in a rigid and technical sense in labor cases before the NLRC or Labor Arbiters; rules of evidence prevailing in courts are not controlling, and Labor Arbiters may evaluate evidence of actual practice even if contrary to written CBA provisions.
• Overtime Boycott as Illegal Strike — A concerted refusal by employees to render overtime work, contrary to an established practice of working extended hours and designed to coerce the employer during labor negotiations, constitutes an illegal strike or a "slowdown," which is inherently illicit as it constitutes working on the employees' own terms while accepting wages.
• No-Strike Clause Violation — Concerted activities such as overtime boycotts and work slowdowns are illicit when they violate explicit contractual commitments prohibiting strikes, walkouts, stoppages, or slowdowns during the term of a collective bargaining agreement.

• "It is fundamental that a statute is to be read in a manner that would breathe life into it, rather than defeat it."
• "In labor cases pending before the Commission or the Labor Arbiter, the rules of evidence prevailing in courts of law or equity are not controlling."
• "Rules of procedure and evidence are not applied in a very rigid and technical sense in labor cases."
• "The Court is in substantial agreement with the petitioner's concept of a slowdown as a 'strike on the installment plan;' as a willful reduction in the rate of work by concerted action of workers for the purpose of restricting the output of the employer, in relation to a labor dispute."
• "The Court views the gesture of respondent company as an act of generosity for which it should not be punished."
