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