Joining Time Rules
1. Whether Joining time / Joining Time pay is admissible in case of technical resignation of a Government servant to join another Government organization?
For appointment to posts under the Central Government on the results of a competitive examination and or interview open to Government servants and others, Central Government employees and permanent/provisionally permanent State Government employees will be entitled to joining time.
A Government servant shall be treated on duty during the period of joining time and shall be entitled to joining time pay equal to the pay and allowances like DA, HRA, CCA, drawn before relinquishment of charge at the old post. But temporary Central Government employees with less than 3 years of regular continuous service, though entitled to joining time would not be entitled to joining time pay. {Rule 4 (4) of CCS(JT) Rules}
