(TELEGRAPH) — Stress at work is leading some teachers to become increasingly reliant on caffeine, alcohol and prescription drugs, while a number have seen relationships breakdown, it has been suggested.

A new poll indicates that more than four-fifths of school staff (83 per cent) think that their job has had a negative impact on their health and wellbeing in the last 12 months.

Given a list of issues and symptoms they may have experienced, some 84 per cent of those polled by the NASUWT teaching union said that they have lost sleep due to their work, while three in four (54 per cent) have experienced anxiousness and a similar proportion (74 per cent) reported low energy levels.
