Republic Drug Co. has 1,000 employees, including 50 managerial personnel, 90 supervisors and 150 sale representatives. The regular workday in the Company is from 8:00 a.m. to 5:00 p.m. The sales representatives register their presence with the timekeeper at 8:00 A.M. every day before they go to their respective sales territories. They are paid a basic salary plus commission. Sixty of the sales representatives are members of the Republic Salesmen Union which sent to the Company a set of bargaining proposals, including a demand for payment of overtime pay of the sales representatives for working beyond 5:00 P.M. everyday. The Company refused to consider the bargaining proposals and rejected the demand for overtime pay for the reason that the sales representatives are not entitled thereto. The Union filed an unfair labor practice case against the Company for refusal to bargain, and after complying with the legal requirements declared a strike. Was the Company legally justified in rejecting the Union's demand for overtime pay? Reason
