What is Migration and its cause?
   1. Movement of people from their hometown to another city, state or
      country for a job, living or some other reasons is called migration.
   2. Both Push factors and Pull factors are involved in the migration
      process. 
   3. Employment opportunities are the most common cause of
      migration. 
   4. Apart from this, lack of opportunities, better education, construction
      of dams, globalization, natural disasters like floods and droughts
      and sometimes crop failure are among miscellaneous reasons.
National Commission for Migrant Labours:
   1. NITI Ayog has constituted a sub-group for preparation of National
      Action Plan for Migrant Workers. 
   2. The group comprises the members from various ministries of
      Government of India, subject experts, NGOs and Civil society
      organizations to prepare a tangible action plan to address the issues
      related to migrant workers. 
   3. Information was provided by Santosh Kumar Gangwar in a written
      reply in Rajya Sabha. 
   4. The act that was earlier governing the migrant workers issues was
      Inter State Migrant Workmen (Regulation of Employment and
      Conditions of Service) Act, 1979. 
   5. This act was subsumed in the Occupational Safety Health and
      Working Conditions Code, 2020.
   6. It provides for proper working conditions, minimum wages,
      grievances redressal mechanisms, protection from abuse and
      exploitation, enhancement of the skills and ensures social security
      to the labourers. 
   7. As per the migration draft, "“should be acknowledged as an integral
      part of development”, and “government policies should not hinder
      but…seek to facilitate internal migration”.
NITI Aayog’s Approaches
There were two approaches put forward by NITI Aayog
i) Handout Approach- This means usage of all the facilities provided by
the Indian Government to migrants
ii) Rights based approach- This approach means the rights must be
ensured in all states
This policy would include the migrant into the political system too. 
As per NITI Aayog, the Government's goal must be to provide a limited
approach. This means 'Don't give the boy a fish, rather teach him fishing'.
The Government must not provide permanent or social aids to migrant
workers rather create opportunities for them. 
Migration must be acknowledged as a process and integral part of
development. Moreover Government policies must be such that they do
not hinder migration.
