Employer's failure to state a valid reason for dismissal violates termination rules under Labor Code Art. 30 and 45.

The Supreme Court dismissed the employer's cassation appeal, upholding the lower court's finding that the employer's dismissal was invalid. The court ruled that the employer failed to specify a valid reason for termination as required by law, constituting a breach of statutory obligations. Consequently, the dismissal was deemed ineffective, and the employee's claim to reinstatement was supported despite the existence of a labor dispute.
