11. Athena Coffee Company (ACC) hired 300 coffee roasters under similar employment terms and conditions. ACC assigned these employees to its three roasting factories in Manila, Laguna, and Cavite. In August 2024, the AAC Manila Workers Organization (AAC-MWO) filed a petition for certification election to represent all coffee roasters including those in the unorganized Laguna and Cavite factories. AAC opposed the petition and argued that the three factories do not constitute an appropriate bargaining unit on account of their different geographical locations. May the coffee roasters in the three factories constitute an appropriate bargaining unit? Explain.
