£300m savings for 'unsustainable' Tata Steel
Tata Steel hopes to make £300m of savings and warned its current performance was "unsustainable".
The company announced last week about 750 of the 1,050 job cuts being made around the UK would go in Port Talbot.
A document seen by BBC Wales showed shedding 394 office staff and 332 from the main workforce would save £50m.
It warned the plant "must significantly improve its performance and reduce costs to survive".
Port Talbot and the Llanwern site in Newport manufactures strip steel products.
The document added another £54m would be saved by mothballing parts of Llanwern.
