This year I quite severely injured myself and had to have an operation leaving me out of work for 3 weeks. The company have included this in my Bradford score which makes it much worse. Other than that in the year where I work full time, I have had 2 sick days off.
The Bradford score is calculated by 'instances^2 * days off', so by including my injury I have hit a Bradford score of 153, which means I got a verbal warning. Without my injury it would have been 4. This means if I have any more sick days off, the company said, they would have a formal meeting as policy (HR + managers). As my injury had massively impacted my Bradford score and is out of my control, is it unfair of the company to use my now large Bradford score to punish me against policy? I've only had 2 individual sick days in the last 7 months, and now if I have another single in the next 5 months I get punished.
