I do not understand what you mean when you use terms like ‘associates’ and ‘legal advisors’.
It is true that there are counsels that take up ‘employers’ cases only and there are those who stand for ‘employees’. You may prefer the latter one.
It should be a commercial establishment and you may not have to tender more than 15 days.
Find out if company has an office at your new location at Haryana or its Redg. Office at your new location or say at Delhi.
The inner wishes of bosses and even employer are neither rule nor law.
The employer/establishment is subordinate/inferior/servant to the law of the land……………………………and this should explain your comments that “"leaving on completion of my tendered notice and today would mean the same…… in both cases for them.”
You seem to have merits.
The bosses are set to disturb you as it is for them a chanced to build some reputation.
However you should not get booged down.
