Employer without union can validly introduce group work regulation under Labor Code Art. 2951 § 1.

The Supreme Court resolved a legal question regarding whether an employer lacking a union can validly implement a group work regulation. The plaintiffs argued that without a union, the regulation was ineffective, while the court noted the absence of union presence did not invalidate the employer's actions. The court decided that the statutory language allows such implementation, emphasizing that workers voluntarily join groups and retain judicial protection.
