The person who initiated this thread has not disclosed whether the Punjab Government Office to which he has referred is an "industrial establishment" or "commercial establishment." If it is an industrial establishment, only then will the provisions of The Industrial Employment (Standing Orders) Act, 1946, and rules as framed by the State Government of Punjab be applicable. The term "commercial establishment" has been defined under relevant shops & commercial establishment Acts (viz. Delhi Shop & Commercial Establishment Act, 1954).
Every office of the State Government or Central Government or UTs has adopted or enforced service conditions and leave rules as per their own decisions and choice in respect of regular/permanent employees. However, in respect of leave rules/conditions as applicable to the employees of contractors engaged by the State Government, in my opinion, only those conditions will apply which are specifically mentioned in terms and conditions of such contracts or, in default, which are mentioned in the Contract Labour (R&A) Act, 1970, and rules framed by the State Government of Punjab under the said Act. Therefore, the person who initiated this thread may kindly ask his contractor about the status of the leaves or conditions of the sanction of such leaves as are made applicable to such contractor employees.
In addition, Rule 25(2)(b) of the Contract Labour (R&A) Central Rules, 1971, lays down that wage rates, holidays, hours of work, and conditions of service of the workmen of the contractor (if not the same as those of employees of the principal employer) shall be such as may be specified by the Deputy Chief Labour Commissioner (Central). A similar provision may perhaps exist in the rules that are made applicable in the State Government of Punjab under the above Act.
As a golden rule, leave, whether it is called casual leave, short leave, or earned leave, etc., is not a matter of right, and the appropriate authority, in this case, the contractor or the authorized officer of the contractor/State Government, can refuse the sanction of any such kind of leave.
