My reason for asking is that I have an example of where a company has flouted almost every rule in terms of maybe a dismissal or redundancy. Should this be brought to the attention of the body that appointed them for this standard as clearly, they are not being met.
Although there is no explicit HR policy, a certified organization must comply with the requirements of HR-related clauses. For example, clause 7.1.4 on the environment for processes operation addresses both physical and human factors. Among the human factors the standard mentions in a note social and psychological factors, which may frame the concerns you expressed.
Anyone who feels that an organization, while certified, is not meeting the requirements of the standard can always formally complain to the certification body that issued the certificate.
