Explanation:

Employment need not mean to be employed under a citizen it basically means to be working and earning, whether under permanent contract or under temporary contract.

Being on vacation do not mean to be unemployed it basically means to be on temporary leaves, and that the leaves might or might not be paid.

Involving one self into family business is also employed.

But a person who is removed from job and then is waiting for a call is clearly unemployed.
