has there been an update on this case since June then? Because that is when Karsten Kaltoft won his preliminary case.
Looking at that in a little more detail, it refers explicitly to extreme obesity - which will be a comparatively small subset of all those generally obese. I'm not even sure that the ruling will help Mr Kaltoft. What the ruling will do is require employers to make reasonably practicable changes in order to accommodate someones disability. It doesn't mean they have to employ them in exactly the same role. A person who lost their eyesight would make a poor lifeguard, for example.
In Kaltofts case, he lost his job as he couldn't tie up his shoelaces - which was dangerous for a childminder. It would not be reasonably practicable to hire a shoelace tier for him, or invent a machine that could so so. I suppose slip-ons might be an option. I'm not sure what effect such a ruling would have upon healthcare, it would vary from country to country I guess, and would depend upon the action the extremely obese person took to rectify the situation.
