THE number of teachers suffering with their mental health is “extremely worrying”, the Education Secretary has said.

A survey by teachers’ union NASUWT found 64% of Scots teachers said their mental health had suffered because of their work in the last year.

More than three-quarters also said their workplace stress had increased over the last 12 months.

Responding to the findings, John Swinney, pictured, said “no teacher should feel like their job adversely affects their mental health”.

“Local authorities as employers have a duty of care for all of their staff, including teachers,” he added.

“The Scottish Government, along with local authorities, is already taking action to address conditions that affect well-being by putting in additional support for teachers to tackle workload issues and improve recruitment and retention rates.”

He added the Scottish Government was “tackling unnecessary tasks and work that teachers are involved in.”

The study shows 75% of teachers were affected by anxiety in the last 12 months, with 83% suffering sleeping problems.

Just over one-fifth (21%) said they are drinking more alcohol, almost one in 10 (9%) has seen their relationship break down and 2% have self-harmed.
