The telecommunications firm has a workforce of 160,000, of whom 110,000 are directly employed while the remainder are contractors, consultants and agency employees - known as indirect staff: 40% of the job losses will involve direct staff and 60% of them indirect staff.
BT announced this morning it has already cut 4,000 of its 160,000 jobs - mostly indirect positions - and 6,000 more will go by March.
A spokesman from BT told HR magazine the programme is to reduce the organisation's dependence on consultants and contractors.
He said: "Thousands of direct staff leave BT every year so this year it is really about us not replacing a large number of those people. In previous years, we have tended to recruit as many new people as leave but this year we want a net reduction of 4,000 direct staff. We will therefore achieve the reduction in our direct staff largely by natural turnover. We have achieved reductions in staff in previous years through voluntary schemes.
"The direct jobs are mostly in the UK, reflecting the fact that approximately 90,000 or our 110,000 direct jobs are UK-based. The indirect jobs are a mix of UK and non-UK and will depend on which exact projects we choose to proceed with in the coming six months."
