A police officer who claimed his line manager harmed his promotion prospects has been awarded £15,000 in compensation.
Pc Fisher claimed his line manager harmed his job prospects
Pc Douglas Fisher, of Kinghome Road, Dundee, had served with Tayside Police for 10 years.
An employment tribunal heard he was threatened with dismissal when he raised concerns about officers going on patrol alone.
The tribunal ruled unanimously in Pc Fisher's favour.
The tribunal in Dundee heard how the police officer raised health and safety concerns over the patrol proposal.
He received a letter from a chief inspector threatening him with "almost certain dismissal" if he disobeyed the chief constable.
The tribunal heard he was warned "if you value your future prospects in this job you will do well to transmit more positive signals".
Mr Fisher, whose beat included the Hilltown area of Dundee, was concerned officers would be working alone between 0700 and 1900.
He produced a motion, signed by almost 70 colleagues, which criticised the proposal and said it could lead to offences going unreported.
Mr Fisher argued his line manager failed to support his application to move up the ranks from constable to sergeant.
Tayside Police had earlier tried to stop the case going ahead, arguing Mr Fisher had not complained through the proper channels, the police health and safety committee.
But the Employment Appeal Tribunal referred to the "offensive" terms of a letter received by Mr Fisher, which was '"job-threatening, if not worse".
Tribunal judge Lord Johnston said: "Any reasonable man receiving that letter would be bound to feel that his job and his whole career in the police force was at stake and that accordingly, he had better not take the matter any further."
