The Solihull plant was threatened with closure

The ballot on whether to accept new working conditions is to be held among the 8,000 workforce on 20 September.

The road map was drawn up by Land Rover's own managers and unions at the request of parent company Ford.

Video cameras will be installed to monitor work and piped music or radios will be banned, the BBC has learned.

Other measures include "bell to bell" working, whereby workers will not be able to down their tools until their shift is over even if they have filled their quota.

The number of shop stewards will be cut from 120 to 85 and the company aims to cut absenteeism from 5% to 3%.

Both Land Rover and The Transport & General Workers Union declined to comment on the plans until the result of next week's ballot, saying some workers had yet to be informed of the full details.

Lagging behind

Ford instructed Land Rover bosses and unions to come up with ways of improving the company's performance in May this year.

The US car giant, which bought Land Rover from BMW in 2000, was concerned that the company was lagging behind its other operations in terms of competitiveness.

The firm, which is heavily dependent on US sales, has been hit by the weak dollar, and its vehicles have performed poorly in quality surveys.

There had been speculation that Ford would shift Land Rover production to its Jaguar plant in Merseyside if the company failed to come up with an acceptable plan.

Meanwhile, Jaguar's Brown's Lane plant in Coventry is under threat after a disappointing performance.
