Unethical and against labour rules!
But the process is unethical and against labour rules. Last year, in the wake of the TCS layoff, the Tamil Nadu government had clarified that employees can form trade unions to redress their grievances by invoking the Industrial Disputes Act 1947.
Three years earlier, Karnataka had tried to lift the decade-long exemption from the Industrial Employment (Standing Orders) Act (1946) that it had granted the IT industry for more than a decade; but had to retreat within a few months under pressure. Given their contribution to the economy and the job market, and their growth potential, the state and central government have always treated them with remarkable exceptions. This blanket exclusion will certainly come under pressure if layoffs become a norm.
