There may be cases where Underperformance does not improve despite the implementation of the Performance Improvement Action Plan.  Where a manager has made concerted efforts to address underperformance in a jobholder and the jobholder has failed to improve his/her performance to a satisfactory standard, the manager can legitimately start disciplinary action.  Taking disciplinary action means that the manager must follow the Civil Service Disciplinary Code which sets out the procedures involved in invoking the disciplinary code.  Before starting to take any disciplinary action the manager should consult with the HR Unit.  For full details see the Discipline section.
