A strike by lecturers is to go ahead after fresh talks between management and union leaders ended without agreement.

The Educational Institute of Scotland (EIS) has said Colleges Scotland failed to deliver on a deal agreed last year, but Colleges Scotland insists the offer it has put forward is fair.

Both parties agreed to a meeting held through Acas in a bid to resolve the dispute, but the EIS said no progress was made and a strike on Thursday will go ahead.

The college body claimed EIS is striking "to get more money for less work", with the union responding by accusing Colleges Scotland of attempting to "peddle 'alternative facts'".

College staff walked out on strike for a day in March 2016 and had more than 30 days of action planned before accepting a revised offer from Colleges Scotland, with staff promised wage rises as well as work between colleges and the union to develop a more ''harmonised'' pay deal across the workforce.

Larry Flanagan, general secretary of the teaching union, said: "EIS negotiators entered into today's talks, under the auspices of Acas, in good faith but were met with yet more management intransigence.

"Management have, once again, refused to honour the deal they signed up to a year ago and so the planned strike for Thursday will go ahead as scheduled.

"Despite what Colleges Scotland are claiming, through their unnamed spokesperson, the EIS is not striking to get more money. The EIS is striking to get the binding agreement made last March implemented - the amounts of money involved have already been agreed and the funding is sitting in college bank accounts.

"The EIS has already demonstrated compromise in the negotiations with Colleges Scotland, negotiations that have already agreed national pay scales, pay migration and harmonisation and most national conditions of service. This dispute could be settled by management simply delivering what they already agreed to last year."

Colleges Scotland said it is willing to take part in further talks.

A spokeswoman said: "The engagement by the EIS is welcome as there is a clear need for the EIS to show willingness to compromise and end the threat of strike action.

"The EIS needs to show a willingness to compromise. They are striking to get more money for less work, when the deal put on the table by employers is not only fair but beneficial as it equates to an average pay rise of 9% for lecturers over the next two years.

"The only thing standing between lecturers and an average pay rise of 9% is the EIS's insistence on 66 days' holiday and a teaching working week of just 21 hours.

"The employers have already agreed the pay rise and proposed a generous package that would provide 56 days' holiday and 24 hours' class contact with the facility to timetable up to 26 hours in any eight-week period, which members of the public will regard as a very good deal indeed.

"In the end, the EIS are calling a strike because they want more holidays and fewer working hours, and that is simply not realistic.

"Industrial action is wholly unnecessary and disruptive for students in the run up to exam time, and we are extremely disappointed that the EIS has chosen to take its members down the route of strikes when talks are still ongoing."
