To take this topic a liitle bit further:
In this Article
Offshore Energy it is suggested that when obese is recognised as a "handicap" the oil operators would have to accommodate.
I think this should be no problem if the operators accommodate in the same way as they currently accommodate for persons in wheel chairs, blinds and (completly) deaf. I.e. They won't pass medical testing.
If the operators and service companies would have to compensate to accommodate with higher percentage "handicapped" for onshore jobs, then they can start widening the doors and strenghtening the floors of the Offices!
