Contract workers - no concern for their safety?

Safety of contract workers is given less importance compared to regular employees. In industrial areas, we can find this difference glaringly. Even the contractor who provides manpower also is not concerned though he may be charging the organization for use of safety appliances by his personnel. These daily wage earners are treated like no entity and the contractors who earn money by using these people are nothing short of leeches. Factory managements and factory inspectors should penalize heavily such contractors so that they feel it is better to provide safety appliances rather than paying the penalty. Ordering the closure of factory also will do good as managements can ensure safety for contract workers also by whatever means it is appropriate. Sometime back I listened to a talk wherein the speaker said that the contractor will be penalized Rs. 5,000/- for every violation and this money is credited into safety awareness fund. After three violations, the contractor will be blacklisted. I feel such measures will help in creating awareness by force among all and ensure safety for all.
