VIDEO: College lecturers protest in Glasgow's George Square

College lecturers are out on strike for a second day in a long-running dispute over pay and conditions.

The Educational Institute of Scotland (EIS) said members were walking out over the refusal of college management to honour a deal that was reached more than a year ago.

The agreement promised equal pay for lecturers in all colleges and national terms and conditions following years of pay inequity for lecturers doing the same jobs in different colleges, the EIS said.

The strike comes after a 96% vote in favour of the action in a recent ballot of Further Education Lecturers' Association (EIS-FELA) members.

More than 4,600 members are eligible to take part in the strike, which will affect about 20 institutions.

EIS general secretary Larry Flanagan said: After more than a year of waiting and watching college managers talk down the agreement that they freely signed up to, Scotland's further education lecturers have simply had enough.

All that lecturers are asking is for the deal that was agreed by both sides to be honoured.

Sadly, rather than working to deliver their commitments, college management have spent the last 13 months attempting to rewrite history and airbrush this binding agreement while simultaneously denigrating the hard-working lecturing staff in their colleges.''

A demonstration was held in Glasgow’s George Square earlier.

EIS-FELA president John Kelly, a lecturer from Paisley, said: Rather than wasting taxpayers' money on spin against the agreement, college management should instead focus on delivering that agreement as promised.''

College staff walked out on strike for a day in March 2016 and had more than 30 days of action planned.

A revised offer from Colleges Scotland was accepted last year, with staff promised wage rises as well as work between colleges and the union to develop a more ''harmonised'' pay deal across the workforce.
