A Gramin Dak Sevak (GDS) cannot get earned leave without a replacement.
The head of the office grants casual leave, but only if a substitute is available. 
GDSs can only get up to two days of emergency leave at a time, and it cannot be combined with paid leave or carried forward.

It takes 3 to 7 days for the dept to inform employee

Central and state government employees are entitled to 30 days of earned leave (EL) annually. This is credited to their account in two installments of 15 days each on January 1 and July 1. Unused EL can be carried forward for up to 300 days.

2) leave cannot  be claimed as matter of right and can be refused by the authorities 

3) arrange a substitute so that your leave may be sanctioned 

Act as mentioned herein above 

you are entitled to earned leave 

You have not stated that your department has rejected your application for leave and also you have not stated if you will be eligible for earned leave as per regulations of India post.

You have drawn the GDS into this subject hence you got the opinion accordingly.

Nothing prevents you from enquiring about the status of your leave application form the head of the department instead of taking up the issue legally without knowing the underlying law.

You may better enquire about the status of your application for leave, if the rejection is not in conformation to the prevailing leave rules then you can plan to initiate legal action as per law.

Guidelines for Earned Leave for Departmental Postman:

1. Response Time for Leave Request:

   • 
     As per rules under the Central Government Leave Rules, the leave sanctioning authority (Inspector/ Postmaster) must process earned leave (EL) applications promptly.
   • While there is no fixed statutory timeline, a response is generally expected within 7-10 working days. Delays without valid reasons can be escalated to higher authorities.

2. Substitute Arrangement:

   • 
     Responsibility for Substitute: As a departmental postman, it is not your responsibility to arrange a substitute (such as a Gramin Dak Sevak).
   • The inspector or postmaster is responsible for arranging substitute staff to ensure services are not disrupted.
   • Your leave request cannot be denied solely because a substitute has not been arranged.

3. What You Can Do Now:

   • 
     Follow Up: Submit a written reminder about your pending leave application to the postmaster/inspector. Mention the date of the original application and request immediate action.
   • 
     Escalation: If no response is received, escalate the matter to the divisional superintendent or the senior superintendent of post offices.
   • 
     Leave Without Sanction: Avoid proceeding on leave without explicit sanction, as it may lead to disciplinary action.

4. Reference Rules:

   • Refer to Rule 8 of the CCS (Leave) Rules, 1972, applicable to central government employees, including postal staff.
   • Leave cannot be unreasonably denied unless there are critical service exigencies.

Dear Client,

Ideally, the process of application of earned leave among postal department employees should be so quick and approved or disapproved within 10-15 days; that again may vary from local administrative procedures adopted for that region. You are not responsible for arranging a substitute like a Gramin Dak Sevak. It is the supervisory authority's responsibility, such as the inspector, to ensure that the service is not disrupted due to your absence. If your leave application is not processed even after due notice, refer the same to your divisional head or seek a clarification in writing so that you do not face any unnecessary delay or complications. You should also meet your union representative if you need to resolve the issue promptly.

Hope that this helps you to solve your problem.
