Each establishment or employer has own set of terms, mere relation and contractor interchange can not enforce the whole set of rules an any establishment either PE or Contractor,
The query is like,
[earlier my contractor had to depute on a site 30 kms distance from my residence, and after rebadging the new work place is 15 kms distance, can i go to fight with new company that i have to travel 30 kms as per previous posting? ]
as neither the contractor has changed nor the different PE, just change of PE has taken place, contractor is same still, as per my understanding the contractor has deputed the person to a different PE, where retirement age is 55 and that is rebadging, which is used by the employee ( remember the contractor has still 60 age bracket as per post)
let the contractor decide that if the new PE ask to retire at lower age, then the contractor can depute the aforesaid employee to another PE where they can permit up to 60
