Scottish college lecturers have begun the first of a series of potential walkouts over pay.
Almost nine out of 10 lecturers who took part in a ballot voted for strike action, on a turnout of 61%.
Colleges Scotland had urged the EIS teaching union to call off the planned national strike and said they were confident a deal could be reached.
Many lecturers are angry at a 1% pay offer and the differences between pay at different colleges.
They claim there are disparities of up to £10,000 a year.
