We currently have a system of four steps in our disciplinary procedure: Verbal warning Written warning Final written warning Dismissal Would this be standard procedure and would we be covered legally?

In short, yes.

The new LRA Code of Practice on Disciplinary and Grievance Procedures hasn’t changed much in its recommendations in the area of warnings and sanctions. The Code encourages informal resolution where appropriate and emphasises that a "quiet word of caution or advice" may often be all that is required to resolve a problem before proceeding down any formal route. So if not already covered in your procedure, I would suggest incorporating an informal stage at the outset.

Where a formal approach is warranted, the LRA prescribes a three step procedure, taking the form of a first oral or written warning depending on the seriousness of the offence, followed by a final written warning
