Outsourcing giant Serco Group Plc has announced its plans to overhaul its management structure, in a move that will lead to at least 500 redundancies.
Most of the jobs at risk are from the company's office at Hook, near Basingstoke.
Outsourcing group Serco is to chop 500 UK jobs as part of a shake-up in the way it provides back-office services to public and private sector organisations worldwide.
Serco, which offers back-office support for a wide range of public & private sector bodies, has plans to merge its business processing operations into one global arm
It will also revamp its UK management structure to boost performance and cut costs.
The company, which employs 35,000 staff in the UK alone, said in a statement, "We regularly review our opportunities, our structure and the way Serco delivers services for out customers and to target future growth."
Separately, Serco announced that it had hit a new £55 million contract with the British Army to give training and support to military staff prior to their deployment on worldwide operations.
Serco has a workforce of around 100,000 people around the globe.
