1. On return to work you are interviewed by your manager,
2. If you have been sick within x amount of days or for x amount of occasions etc then you trigger a review period.
3. If you are sick again during your review period then you will move on to the next trigger stage.
4. If you trigger too many occasions then you could possibly (in theory) be disciplined or sacked.
It is not helpfull when you ring in sick that your manager says "you do realise that this will trigger stage four of the absence management policy?"
This is what is perceived as bullying and disrespectfull.
