I've had to sit down with them for a "written warning" when I hit two points, at which point I did voice my concerns. They gave the impression that while getting points was automatic, interpreting the points was more on a case-by-case basis and that individual situations would be taken into account when reviewing them. I don't know how they intend to determine which absences are due to actual sickness versus just wanting to take a day off. I know all of my co-workers have complained among ourselves, but I'm not sure if that company-wide resistance has made its way back to HR or not.
