Currently there are trainers, managers and inspectors in various industry sectors, including: healthcare, care, education, door supervision, security and close protection, who are either expected to train, manage, provide guidance on, investigate and even discipline staff who use physical force in the workplace.
This leaves the employer, trainer or manager open to a legal challenge if a wrong assumption was made that led to a decision to discipline or terminate someone's employment or to charge them with a crime. That can end up with the employer facing an employment tribunal or being sued; because someone who has had their rights infringed has "an enforceable right to compensation" under the law.
Worse still, incorrect information, advice, guidance and instruction can lead to an increased risk to staff and the population they serve and if that led to a serious injury or death then the employer and the manager/director responsible can be prosecuted under Health & Safety legislation and in the latter, under the Corporate Manslaughter and Corporate Homicide Act.
