How are the activities in the economy classified on the basis of employment conditions?

Economic activities are classified into two types on the basis of employment conditions (i) Organised sector The organised sector covers those enterprises or places of work where the terms of employment are regular and therefore, people have assured work.
They are registered by the government and have to follow its rules and regulations which are given in various laws such as the Factories Act, Minimum Wages Act, Payment of Gratuity Act, Shops Act etc.
Examples are Reliance Industries Limited, Tata Motors etc.
(ii) Unorganised sector The unorganised sector contains enterprises not registered by the government. The unorganised sector is characterised by small and scattered units, which do not follow proper rules for employment or give any leaves or other benefits. Examples are casual workers in construction, shpps, garages etc.
