Well said, Mr. Bhanot, I completely agree with you. HR professionals cannot shrug their shoulders just by saying 'it is company policy.' They are supposed to suggest and decide the HR-related policies based on prevalent law, best industry practices, sound logic, prudence, and of course, common sense. In case there are some policies not concurrent with law and sound logic, then HR professionals should make efforts to change them.
By the given logic (which is wrong), if all months are treated as 30 days, then why make an exception for February?
If the monthly salary of Mr. X is Rs. 5000, it simply means that Mr. X is getting the same Rs. 5000 for 31 days of January, 28 days of February, 30 days of April, and so on.
Just apply common sense, consider the actual days in the month, and be happy. This is the most commonly followed and right policy.
In this thread and in many other threads, HR people are worshiping the "Company's Policies" as the only gospel for them. This is a great misconception. The law is the only policy. The Company's Policies cannot override the provisions of the various laws under which the establishments govern. Rather, the company's Policies must be in conformity with the law. Any policy that is not within the purview of the law is ultra vires ab initio.
Now comes the point of treating February (in view of treating a month of 30 days). Why was this question not raised for the seven other months, i.e., Jan, Mar, May, Jul, Aug, Oct, & Dec? It is a matter of common sense that the wages earned for that many days are as much as there are in a month. The right for both employee and employer is to get and pay the equitable amount as much earned in a particular month.
I don't understand what is rational about treating every month as a month of 30 days. By doing so, the employer pays for 30*12=360 days only and saves money for 5 man-days per person per year. This is against the law.
