Barclays is the latest bank to cut jobs
Barclays is to cut at least 2,100 jobs globally across its investment banking and wealth management businesses, the BBC has learned.
The move came as it said it was reducing staff to match the "current market conditions".
It is thought 1,300 jobs will go at investment arm Barclays Capital, 500 axed at Barclays Wealth and 330 trimmed at Barclays Global Investors.
The Unite union said that 500 of the total jobs lost would be in the UK
Earlier this month, the bank announced that about 400 other jobs would go - mainly in its IT departments in Cheshire and London.
"We can confirm that we have begun a process to reduce headcount across some parts of our investment banking and investment management units to ensure that we are appropriately sized given the current market conditions," a bank spokesman said, without confirming numbers or where the job losses would be.
"We will continue to hire selectively across those parts of the business that are growing."
The cuts would be equivalent to about 7% of its workforce.
Unite accused Barclays of failing to give workers the full picture of plans for staffing levels.
"We have stressed to the bank that they should come clean with their staff in order to reassure them that they will not be the next victim of the bank's strategy of death by a thousand cuts," said deputy general secretary Graham Goddard.
"In this economic environment, it is not acceptable for Barclays staff to arrive at work each day with the dread that they could be next in what appears to be a lottery of job losses at Barclays."
In November, Barclays shareholders voted overwhelmingly in favour of a plan to raise £7bn, mainly from investors in the Middle East.
It decided against taking money from the UK banking bail-out package because of the stipulations attached, which would have included restrictions on dividends, having government representatives on the board and a requirement to put its UK interests ahead of those of the bank overseas.
