Dear Mr. Ashok,
I regret to say that this type of classification is solely a matter of practice. As I have also pointed out, employees are expected to include managerial staff. However, when the position is questioned, it falls outside the scope of 'labour,' and we struggle to confine unskilled, semi-skilled, and casual labor to the intended term. Due to the rising cost of living and wages, most laws now apply to those earning up to Rs 10,000. In light of this, and with the emergence of workers being replaced by Knowledge Centres, why not refer to all workers as employees?
