The Baby P case has sparked a recruitment crisis in the social care sector as local authorities struggle to deal with an increase in referrals.
Haringey Council has called on other authorities to lend "good quality" social workers for a month to get it through a "real pinch point" of assessing cases of suspected abuse, according to leaked e-mails obtained by the Guardian.
Yet the newspaper revealed that some councils were unable to help.
A Haringey Council spokesman told Personnel Today he was confident Haringey could work with other authorities to ease the lack of social care workers.
"We are in contact with a number of organisations, including councils and charities, to take forward our improvement work and have already received support from other local authorities," he said.
"We want to ensure that sufficient staffing resources are available to deliver social care services. An action plan is being prepared to take forward the issues arising from the Joint Area Review, including longer-term plans for staffing."
