Lloyds Banking Group has announced details of up to 1,000 job losses, part of previously announced cuts of around 9,000.
Unions said they were pressing for no compulsory redundancies and for staff to be redeployed.
The reductions are in retail, commercial banking, human resources, group products and marketing, consumer finance, risk and finance.
About 150 new jobs will be created in groups including retail.
A statement said: "Lloyds Banking Group is committed to working through these changes with employees in a careful and sensitive way. All affected employees have been briefed by their line manager today. The Group's recognised unions were consulted prior to this announcement and will continue to be consulted.
"The Group's policy is always to use natural turnover and to redeploy people wherever possible to retain their expertise and knowledge within the Group. Where it is necessary for employees to leave the company, it will look to achieve this by offering voluntary redundancy. Compulsory redundancies will always be a last resort."
Rob MacGregor, national officer of Unite, said: "Once again we see Lloyds Bank seeking to make short-term 'savings' at the expense of both the workforce and customer service.
"Unite's overriding concern is to challenge and avoid any compulsory redundancies. Following negotiations the bank has committed to providing alternative jobs, voluntary redundancy and voluntary job swapping where possible.
"We will make sure the bank keep to these commitments, while continuing to consult and support our members."
