UNISON staff outside Shawlands Academy in Glasgow were among some of the union's 70,000 members working for local councils who took strike action on Tuesday. A number of schools, but not all, were forced to close and the work of education departments was affected.
The one-day strike in protest against the employers' 2.5 per cent pay offer is set to be followed by another two days of action around September 13-14 and then a further three.
Selected groups of employees will also becalled out on an indefinite strike.
The stoppages are in support of the union's claim for a 5 per cent rise or pound;500, whichever is greater, and a minimum rate of pound;5 an hour. Any "substantial improvement" which falls short of that will be voted on.
Unison complains that the offer is half the going rate for pay settlements at a time when council staff are paid an average pound;17.50 a week less than English counterparts. It is the first strike by council workers in 11 years.
