As a BA newbie I am also looking closely at the pension scheme. Having just received my contract with the pension breakdown within I first laughed at the address of 'Terra Firma' and then got down to reading it.
As with P.T.Gamekeeper I come into BA with an active pension which rose tints my outlook a little. The rest I am intending to take to a finacial advisor to see what additional voluntary contributions could be made.
Unfortunately poor pension deals seem to be the current beast. I would not even comtemplate culling an established system to fund the pensions of those younger to the company. Imagine the animosity that would generate. The pension details were laid out clearly at the interview and therefore comes as no surprise. I, personally, will be AVC'ing in order to leave with a decent living.
Start saving boys and girls, the wage is good in comparison to your average office worker! (Granted they didn't have to mortgage their first newborns soul to pay for the licence

)
Remember, the light at the end of the tunnel could well be an oncoming train.
