Dear Sirs,
Let us see what the law speaks about WC applicability. I feel that salary is not the criteria for considering WC coverage.
It is the type of industry and the type of work the person does, which enables him or disables him from being eligible for compensation.
The definition of "workmen", is described in Schedule II of the WC Act where the categories of work eligible for WC is listed out.
In reality, it is very difficult for anybody to talk the law when one is to show concern & sympathy.
Hence instead of differentiating amongst employees & seeking exemption, it is better to have a coverage, taking into view the larger interest of the company and to ensure peaceful running of business. Taking a policy reduces your risk as you stand indemnified from claims.
Injury need not always be fatal. It could be temporary, partial or permanent. So cost of treatment would exist, which could be set off by way of a medical insurance policy.
These are welfare measures which are "beneficial" costs to company as they save for the company in the long run.
Think it over.
regards
