India Possesses nearly 2.4 percent of the total land area of the world, but has to support about 1.4 billion population (about 17.7 % population of the world). The term density of population implies the average number of person living per square km. Here the denominator is fixed and the numerator is constantly increasing. As a result density of population increases, the moment an additional birth take place. Industrialisation has led to the problem of urban slums, where a small room is shared by a number of persons. Everywhere, a crowd is found. Frequent lockdowns in phases (1st phase from 24^th March to 14^th April 2020, 2^nd phase 15^th April to 3^rd May 2020, 3^rd Phase 4^th May 2020 to 17^th May 2020 and 4^th Phase 18^th May 2020 to 31^st May 2020) have been declared by the government in order to check the corona virus 2019. Social distancing is the only way for protection. All activities have been stopped. Some relaxations have also been announced for a limiting set of economic activities. Pockets have been classified into categories of red, orange, green and containment zones. Opening of offices and shops to a limited degree has been ordered. Migrant workers have left to their hometowns- where job opportunities are not there and these states will have to create jobs for them. When economic activities would start, for example the operation of MSME and large industries, there will be an acute shortage of labour (particularly of semi-skilled and skilled labour). Definitely there would be a gap when they are likely to return back along with unnecessary bearing of relocation costs. Northen and eastern states provide supply in the labour market. They were so desperate that they were undertaking the risk of movement of long distance on foot along with their family members including babies in arms. Some states have also adopted labour reforms- like hiring and firing policies, fixation of wage rate, increase in working hours etc. This paper is an outcome where labour laws are being amended along with so many challenges and uncertainties.
