A third of teachers say they would opt for a different career path if they could make the choice again, according to a new survey which highlights the impact of workload on staff morale.

The research, published by the National Association of Schoolmasters Union of Women Teachers (NASUWT) Scotland, also found only half of teachers feel satisfied with their job, and the majority do not feel their profession is valued in society.

The union said the findings indicated that staff morale and professionalism is "being seriously damaged".

Almost 1400 teachers working in schools across Scotland responded to the survey carried out by the University of Stirling on behalf of NASUWT.

It found 54% would still choose the profession if they could decide again, with 50% agreeing they were satisfied with their job.

But 33% said they would opt for a different career, and 72% disagreed with a statement that "the profession is valued in society".

On workload, based on a scale of one to 10, with 10 being the highest, 60% of secondary school teachers and 50% of primary teachers rated their workload as being at nine or above.

Nearly two-thirds (63%) of teachers said they took work home three times or more each week, and nearly six in ten (58%) reported they had after school meetings almost every week.

Meanwhile, over half (53%) reported there was a teacher shortage in their subject area at their school, with 83% saying this had impacted on their workload.

Chris Keates, NASUWT general secretary, said: "The year-on-year decline in teachers' pay and working conditions since 2010 has spawned a growing teacher recruitment and retention crisis.

"This will only continue to deepen without urgent action to address uncompetitive pay levels and excessive workload."

Similar concerns over workload have been raised by other teaching unions, including the Educational Institute of Scotland (EIS).

Its survey, published earlier this month, found 85% of respondents reporting an increase in workload in the past year.

A Scottish Government spokesman said: "We have undertaken a range of actions to ensure a reduction in teacher workload, acting to clarify and simplify the curriculum framework and to remove unnecessary bureaucracy.

"We are putting in place new career pathways to provide opportunities for teachers to diversify their career and support high-quality teaching and learning while helping to deliver improved outcome for pupils."
