School janitors across Scotland's largest city will go on strike for the full first week of the new term.

Unison trade union members employed as janitors in Glasgow's primary, nursery and additional support for learning schools will take further strike action next week as a long running dispute over pay continues.

The five-day strike will begin on the first day of the new school term amid an ongoing dispute over pay and conditions.

The strikers will protest outside the city chambers on Monday and Thursday and leaflet parents at the school gates every day.

The janitors began industrial action on January 19, this year, by boycotting weeding, litter picking, snow clearing, salt spreading, leaf clearing, heavy lifting, spillage clearing and animal clearing.

Schools cleaners, catering staff, education support workers, teachers and headteachers have all been advised by their trade unions not to undertake the duties which the janitors are boycotting.

Since March, the janitors have taken nineteen days of strike action in an escalation of the dispute. Unison says its members have been left with no option other than to take this action as both Cordia and the council are "wrong and refuse to listen."

Cordia, an arms length organisation of Glasgow City Council, is refusing to pay a Working Context and Demands Payment (WCD) to school janitors.

The union also claims it is using "spurious arguments to justify not making this payment". There are five levels of annual WCD payment ranging from just over £500 to over £1000.

The council is now undertaking a "review" of janitorial services across the city with the impact on jobs, wages and conditions unknown and no timescale for its completion.

Brian Smith, Unison branch secretary, said: "The payment due to our members for these duties means that they lose earnings of £500 to £1000 every year. We are sure that parents will understand that it would be wrong for this unfairness to continue.

"Cordia has spent thousands of pounds every month since January 2016 trying to undermine our official boycott of the duties through the use of non-trade union replacement workers.

"They would be better getting round the table and sorting out our legitimate claim."
