Disciplinary issues arise when problems of conduct or, in some cases, performance are identified by the employer, who consequently seeks to address them. 

You must follow the ACAS Code of Practice on discipline and grievance if your employee has at least 2 years of continuous employment, although it is good practice to implement and apply a disciplinary procedure equally to all employees, irrespectively of the length of their employment. 

If your employee brings a successful unfair dismissal Tribunal claim, the Tribunal has a discretion to adjust any award up to 25% for your failure to unreasonably comply with any part of the Code.
