Hello friend.
I am no longer regular on this platform. But as a Government official, I know this rule (technical resignation). You have joined a new Government office after tendering a technical resignation in your previous Government office. Please read your relieving order very carefully. Has it mentioned your increment date? Has the relieving order mentioned anything about the lien in your previous post? All these are important.
I myself tendered technical resignation to join a post with higher pay-scale. As an officer dealing with Establishment (personnel) matters, I know very well that in case of technical resignation, your previous service period will be counted and the leave accumulated will be carried forward in the new office. But, you will not get any benefit regarding the date of increment.
Your date of increment in the new office will be calculated on the basis of your joining date in the new office. The date of increment in the old office has no relevance.
