Before using these procedures you and your employer should attempt to resolve any dispute informally where possible.
The statutory grievance procedures introduced by the Dispute Resolution Regulations must be followed by all employers and employees if a complaint is formalised. These are only a minimum standard and some employers may already have grievance procedures which go further. It is important to note that they do not apply to other workers such as sub-contractors or freelance workers.
You should obtain advice on whether and, if so, how the procedures apply to you from your trade union representative, local Citizens Advice Bureau or ACAS.
