SENIOR officers at Police Scotland are being asked to reject overtime and stick to “core duty hours” as frustrations over their long-running pay and staffing dispute escalates.

The Association of Scottish Police Superintendents (ASPS) says its ranks have seen “unprecedented reductions” in recent years, putting “unsustainable demands on those who remain.”

Writing to Chief Constable Jo Farrell, ASPS general secretary Stewart Carle said the effective overtime ban had “become necessary to safeguard the health and resilience of our members.”
