finds that 92 per cent of chaplains provide pastoral care for students, 91 per cent do so for staff and 76 per cent do so for the headteacher.
Joy Hawes, chaplain of the Blue School in Somerset, said that because chaplains were "a bit outside the normal hierarchy", they were well-placed to support teachers.
"Because I'm not a teacher myself I have a different perspective and I look at people in terms of the whole of their life," she added. "Teachers do feel able to talk to me about the tricky issues of their working life, but it's also about what's happening outside work."
Julian Stanley, chief executive of the Teacher Support Network, said there had been a 6 per cent rise in the number of education professionals seeking support from counsellors via the charity's helpline last year. The main issues raised included anxiety, stress and the "ability to say no at work".
"Evidence from our recent health survey emphatically shows that pressures at work, such as workload, demands from managers and student behaviour, are resulting in significantly high reports of stress, anxiety and depression," Mr Stanley said.
"It is important that teachers find someone to talk to about these kinds of issues, whether that's with a chaplain at school, via our helpline or with friends and family, so they do not suffer alone."
Richy Thompson, campaigns manager at the British Humanist Association, said the growth of chaplaincy raised "questions as to whether funds are being taken away from teaching, or from more inclusive forms of pastoral support such as counsellors".
"It is vital that any support provided is inclusive of all pupils and staff, and where an individual is employed explicitly on account of their religious opinions this instantly puts a barrier up," he added. "It also raises wider questions about the appropriateness of state funds being used to prop up religious groups."
Gogglebox's Rev Kate: `People talk to me about work pressures'
The Reverend Kate Bottley may be best known for sitting in front of the television on Channel 4's Gogglebox, but she also works three days a week as a chaplain for North Nottinghamshire College.
The former secondary RE teacher says that while chaplains have long been perceived as the "poor cousin of ordained ministry", she enjoys working on the front line - especially with young people who "might never darken the door of a church".
Her role is paid for by the Diocese of Nottingham and, given the financial pressures in the further education sector, "I suspect it wouldn't be funded if the diocese didn't pay".
Rev Bottley offers support on a wide range of issues, from stress and bereavement to "sex, drugs and rock and roll". "Everything that's part of the life of the college," she adds.
"Sometimes people are scared that chaplaincy is going to be about indoctrination and preaching to convert - that's not why we're here," says Rev Bottley. And a growing part of her role is supporting staff.
"I have had people come and talk to me about the pressures at work; the challenges and frustrations of what it means to be in education at the moment."
But the role does bring some light relief. "I spent one day dressed up as a cigarette, hanging out in the smoking shelters for No Smoking Day," she says. "It's like being a vicar without portfolio - I get to make up my own job. I love what I do."
`Not just a dog collar'
The Reverend Neil Dunlop, chaplain of North Warwickshire and Hinckley College, has developed his own approach to building relationships with staff.
"Every Friday I go around every member of staff and offer them a sweet," he says. "It's a really good opener and it means I'm connected with all staff.
"It's about raising the profile of the chaplaincy so that if there's an issue they want to talk about, they know I'm not just a face with a dog collar but someone they can talk to. I get called the candy man, but I don't mind.
"When I started handing out the sweets, two years ago, it would take about half an hour to get around the staff," says Rev Dunlop. "Now it takes three to four hours, because people are starting to feel they can open up to me about issues."
