Staff at volunteering charity WRVS have been told they could face redundancy as the organisation restructures in a bid to win more contracts with local councils and primary care trusts.
The charity, which has 2,500 staff, has proposed cutting 70 senior management posts and creating 52 regional manager positions.
WRVS said the changes would make the charity more efficient at working in partnership with other charities and tendering for contracts.
A self-commissioned independent report into the organisation, published last month, said some commissioners thought of WRVS as "cliquey, self-absorbed and weak in networking and partnership". The charity "was not really aware of local authority priorities for service delivery", it said.
Lynne Berry, chief executive of WRVS, said it was consulting regional managers, project managers and volunteers about the restructure.
"Feedback from the report showed that commissioners and beneficiaries were unsure of who to approach in WRVS, so we are making our management structure clearer and more efficient," she said.
