Understanding Leave Entitlements Under the Delhi Shops and Establishment Act
The leave part is governed by the Shops and Establishment Act or, alternatively, the Factories Act. These rules are more or less the same. Let me quote the leave section of the Delhi Shops and Establishment Act.
22. Leave.—(1) Every person employed in an establishment shall be entitled—
(a) After every twelve months' continuous employment, to privilege leave for a total period of not less than fifteen days;
(b) In every year, to sickness or casual leave for a total period of not less than twelve days:
Provided that:
(i) An employee who has completed a period of four months in continuous employment shall be entitled to not less than five days' privilege leave for every such completed period; and
(ii) An employee who has completed a period of one month in continuous employment shall be entitled to not less than one day's casual leave for every month:
Provided further that a watchman or caretaker who has completed a period of twelve months in continuous employment and to whom the provisions of sections 8, 10, 11, 13, and 17 do not apply by virtue of an exemption granted under section 4, shall be entitled to not less than thirty days' privilege leave.
(1A) (i) Privilege leave to which an employee is entitled under clause (a) of sub-section (1) or under any such law, contract, custom or usage, award, settlement, or agreement as is referred to in section 3, or any part of such leave, if not availed of by such employee, shall be added to the privilege leave in respect of any succeeding period to which he is so entitled. However, the total period of such privilege leave which may be accumulated by such employee shall not at any one time exceed three times the period of privilege leave to which he is entitled after every twelve months' employment under that clause or under such law, contract, custom or usage, award, settlement, or agreement.
(ii) Leave admissible under clause (b) of sub-section (1) shall not be accumulated.
(2) If an employee entitled to leave under clause (a) of sub-section (1) of this section is discharged by his employer before he had been allowed the leave, or if, having applied for and having been refused the leave, he quits his employment before he has been allowed the leave, the employer shall pay him full wage for the period of leave due to him.
Here, if you see, the leaves, even if you start giving due to custom, will be over and above what is otherwise payable to an employee.
