They have been urged to refuse calls to go into work when off-duty amid a protest over a pay dispute with the Scottish Government. The body that represents rank-and-file officers have demanded a “fair and justifiable” pay rise of 8.5 per cent.

Officers cannot legally strike or take any form of industrial action and made the pay increase request a few months ago but have yet to get a response from the SNP executive. They have now been urged to work-to-rule in a bid to force discussions about their wages.

Officers have been urged not to report for duty when they have time off, not working when they feel ill and not to accept anything less than regulatory entitlement. The Scottish Police Federation (SPF) has claimed that the pay demand has come at a time when the force is “stretched beyond the limit”.

Off-duty officers staged a protest outside Thursday’s meeting of the Scottish Police Authority as they demanded that talks about their wage rise are pushed forward.

Chairman of the SPF David Threadgold claimed he knew of one officer who should have had 60 days off in the first 30 week of the year, but had 24 days off disrupted where they had to work instead.
