Deise I presume that your tongue is firmly in your cheek there - either that or your head is somewhere else! 99.9% achieving increments is as close to guaranteed as you will ever get.
Just out of curiosity, what percentage of those employed in the public sector have regular dealings with members of the public (i.e. teachers, nurses, gardai, librarians, etc.)? Also, as Purple said, what is being measured in order to know whether any of these are performing to expectations? All any of those surveys show is that front line public sector workers are perceived to be doing their job. There is absolutely no way members of the public would have any clue how these workers are performing against targets/expectations as we have no clue what those targets/expectations might be.
