I would assume that all ex UK "Government Employees" in Scotland would continue to be Taxed by HMG - which is of course paying their Pensions!!
Why would HMG (I am assuming you mean HM's UK G?) be paying their pensions? If an independent Scotland are claiming 8-9% of the UK coffers/military/etc, they should also take on paying 8-9% of the current public-sector pension burden
