Length of service, number of violations to be considered in penalizing employees

Even when an employee is found to have transgressed the employer's rules, in the actual imposition of penalties upon the erring employee, due consideration must still be given to his length of service and the number of violations committed during his employ. The penalty must in no case be unduly harsh and grossly disproportionate. [G.R. No. 105396. November 19, 1996]
