Unscruplous operators exist in any business or industry. Even in the manufacturing industry, one finds factories that do not overwork their employees and offer them excllent work conditions. On the other hand there are people running "sweatshops" that flog their workers. In the absence of effective implmentation of labour laws, these outfits will always flourish.
Fact is, people like Subhash Mukherjee always have a choice. To choose a more employee-friendly organisation. And there are many. To demonise the entire industry, because of one bad experience is not right.
