God you lot are so cynical. Don't get me wrong I know this lefty government wastes way to much of our money on useless people and projects but at the same time if things are going to change you have to attract the people of the ight calibre from the private sector into public sector jobs. Otherwise it just ends up as promoting from within and nothing changes.
Bonus for this type of job is calculated on performance which will be an overall evaluation of the job was performed the tasks set by the authority and how they were completed. Overall performance of the authority based on the public audit etc.
