Up to 59 jobs could be at risk at Christian Aid as part of an internal reform programme, the charity has said.
A spokeswoman for the development charity said the posts at risk of redundancy were mostly in the charity’s supporter and community partnerships department and its international department.
The positions identified are at Christian Aid locations in the UK and overseas, spokeswoman said.
Christian Aid employs 952 staff worldwide, some of which work part time. Christian Aid said the reductions would amount to a 6 per cent reduction in full-time equivalent posts to 890 globally.
The spokeswoman said the charity was at the beginning of a consultation process about its plans before it released its final proposals in December.
She said other changes would centre on strengthening Christian Aid’s relationship with its supporters, making the charity more proactive in its work with major donors and also increase its capacity to campaign and fundraise through digital channels.
Further details would be released once a consultation on the proposals had been completed, the spokeswoman said.
Loretta Minghella, chief executive of Christian Aid, said the charity wanted to strengthen its relationships with supporters and to update its technology while also addressing changes to fundraising in the past few years.
"Our overall income remains strong but we are responding to an increasingly challenging fundraising environment and our experience of how people prefer to approach their giving," she said.
"We are also very conscious of changes in the institutional funding context and in exchange rates, as well as the need to balance investment with the maintenance of appropriate reserves.
"Power, money and technology are all shifting in the world and we have to change, too.
"What we are doing will help ensure Christian Aid weathers these changes and continues its high-quality, high-impact work for many years to come.
"We recognise that the transition will be hard for some of our staff and partner organisations but believe change is essential, if Christian Aid is to remain at the forefront of fighting poverty into the future."
According to the Charity Commission website, Christian Aid had an income of almost £100m in the year to 31 March 2015, as well as expenditure of more than £94m. But this was a 4 per cent fall in income from the previous financial year.
