The scrapping of the CBD Metro has not only cost NSW taxpayers $330 million, it has also cost more than 350 jobs.

The government said it had not figured out what to do with 43 permanent staff and 20 temporary staff employed by the now defunct Sydney Metro Authority.

Almost 300 people who have provided engineering, design and planning services may also require compensation.

The Premier, Kristina Keneally, would not put a figure on the expected cost of redundancies and terminations. ''It would not be possible to give any figure on redundancies until we've had an opportunity to work with those employees on an individual basis.''

Labor's policy of no forced redundancies means public servants whose positions are axed are redeployed. They remain on full pay for up to a year, after which they can be forced to take redundancy if a suitable role has not been found.
