Legality
Some Crime Acts make it illegal for anyone to interfere with police in the course of their duty. Thus anyone calling on police to stop work or support a fellow worker would be guilty of a criminal offence. Police officers do not have the employment rights enjoyed by other workers because of the nature of the job they do on behalf of the public.
In the United Kingdom Police officers are currently banned from taking strike action under the Police Act 1996. The police have been banned from striking since 1919, when the Police Act was first established. The Police Federation of England and Wales is to ballot rank-and-file officers on moves to overturn the law.
