well as the bonuses are exstremely high they would need to charge customers more to advertise. Then the bosses would want a bigger cut of the funds.
NTL's top bosses are only in for what they can get out not to improve the service or supply the best possible service to the customers. If they was they wouldn't take the bonouses and they wouldn't get rid of the best workers but the worst.
Think about the time Barcley resigned he was on a tape where I heard he was asked about the bonus and if he thought he was given the large bonus for failure he agreed.

but still took the bonus and then more than most customers can earn in a life time as a daily wage to advise..
