9. Lazara Corporation (LC) and Lazara Employees Union (LEU) forged a collective bargaining agreement (CBA). During the freedom period, a certification election was conducted where LEU lost to Samahan ng Manggagawa sa Lazara (SML), a rival union in the same establishment. SML then sent a letter to LC demanding for renegotiation of the existing CBA. LC refused to renegotiate the CBA claiming its validity for two more years. SML filed a notice of strike against LC on the ground of Unfair Labor Practice for the alleged refusal of the latter to comply with its duty to bargain collectively. Is the notice of strike meritorious? Explain briefly.
