The chairman of G4S has indicated that senior managers may be in danger of losing their jobs following the security company's failure to recruit sufficient staff for the Olympic Games.

The Financial Times on Monday quoted company chairman John Connolly as saying "it would be right to consider whether any members of the senior team are best placed to take the company forward."

Connolly added that he wanted to avoid any knee-jerk reaction.

Britain is calling in 3,500 troops to cover the positions G4S could not fill.

The company said Monday its loss on the contract would range between 35 million pounds and 50 million pounds ($54 million-$78 million) in this financial year.
