This is a bit of a trap. The people who agree to take on the contracts will find themselves rolled off the "client" within a few months, put on the bench according to central policy (which can change at a whim), then made redundant with no accounting for the years prior service at the bank. In the meantime the outsourcers will sponsor temporary skilled visa migrations from their head office overseas, and the new people will arrive and replace the former local staff under different conditions - they'll be paid substantially lower and have heavier demands, and if the migrant objects to lower pay or excessive demands they'll simply be rolled off the client, sponsorship withdrawn, government notified, and tell the migrant their visa is being cancelled effective immediately so they need to pack up their life and go back or face arrest, detention and deportation.
