TEACHERS across Scotland are being “morally blackmailed” into “toxic” levels of unpaid work, a teaching union has warned.

Using his address to the annual conference of the Scottish Secondary Teachers Association (SSTA) today, the union’s president Stuart Hunter told delegates:  “I am certain that many, if not all of you, recognise the sources of work that increase our workload from normal to excessive or toxic.

“We have created a culture whereby teachers cannot say ‘no’ because it will not look good for them, after all, ‘it’s for the sake of the kids.’
