Mr. Saravanan,
Had you asked for my opinion, as per the provisions made in your CSO, I would have been much pleased to provide my opinion.
In labour and service laws there is no exception to use discretion of the management. Penalty is something else, but that too needs to be included in the Standing Orders, not to be imposed arbitrarily merely at the discretion of some negative minded HR personnel. You can include even 3 or 5 days cut of salary for one day's absence in the Standing Order, but with due consent of the respective trade union and finally on the satisfaction of the certifying authority, but no conventional or arbitrary penalty can be imposed on any worker.
No doubt uninformed absenteeism affects production, project delivery and other losses to the employer, but if that happens, that clearly vindicate about the incapability and incapacity on the part of the management for inapt handling of the situation or by keeping imperfect conduct and discipline rules.
A pertinent question arises, what for the managers are appointed to over see, manage or control the work & conduct of the workers or to see the productivity unaffected?
Mere punitive measures of the management, that too conventional, can't ensure production, project delivery or cut in losses to the employer. Rather that tends to workers unrest that sometimes become unmanageable to control on the part of the management. Only a positive attitude of the management can ensure productivity and discipline on the part of the employees.
