Dear friend,
Let's not debate whether it is ethical or unethical. What your management says is to be a disciplined person, that is all.
You mentioned you had joined a couple of years back. No management, person, or even a teacher at school goes for such a harsh punishment at the first instance. Maybe your management would have sent a circular, communicated earlier to your staff to be self-disciplined. Despite their efforts, employees may have been careless in adhering to the system. Then this kind of punishment would have come into force.
As our former President Dr. A.P.J. Abdul Kalam said, in Singapore and other countries if you throw a chocolate wrapper, within no time there would be a policeman in front of you to collect a fine. The same person, when in India, might spit in elevators, throw rubbish on the road, or even urinate on the street corner; because there are no strict rules here and people behave as per their convenience.
In foreign countries, people follow the rules and systems without feeling pressured. How many people wear helmets (though it is for their safety); when fines are imposed, people start wearing helmets not just for their own benefit, but with the fear of losing money.
Imagine if some foreign visitors come for business dealings with your company and tour your office. If papers are scattered and things are not in order, what would they feel? Therefore, there is nothing wrong with being disciplined and clean.
Secondly, in my office, many people use cell phones during work hours, wasting time talking to friends and family. Some employees visit others' workstations and chat, wasting their time and others' time as well. If these behaviors persist, where is the productivity? I personally call them out and warn them, and if they do not change, I ensure it is addressed during performance reviews or at the time of increments (again, it affects their monetary benefits).
When we visit a vegetable shop to buy 'ladies finger,' don't we break the tips and ensure we buy only tender ones? For paying some 10 or 15 rupees, we expect quality; what is wrong with expecting quality from people when the management pays you some 10-15 thousand rupees?
If you observe the repercussions of this system, as our friends mentioned earlier, there might be some attrition. However, there would be attrition regardless. If you are not convinced or unable to convince your colleagues, you always have the choice of finding a job more to your liking. Even if you move to another organization, there might be different issues that you perceive as worse than in the previous organization. How long can you keep changing jobs? Just think.
