Hypothetically, if a colleague has repeatedly demonstrated the utter lack of reading comprehension skills (like pulling the same door labelled "push" for the hundredth time), what job could one suggest for them where this "disability" wouldn't be detrimental?
The example you've given is likely not a problem with reading comprehension but obliviousness. I read and understand things very well (I have to read and correct engineering drawings and schematics and implement them), but I simply don't notice a lot of what goes on around me.
My suggestion for that is any job that doesn't require safety, physical team labor, or security.
Interesting that you don't think those occupations require safety or physical labor. I'd hate to see how you clean, operate large equipment, or fuck if you're gonna dismiss safety and labor in doing so.
I don't know where you live, but most off shelf cleaning supplies around here are safe to mix. The strong industrial stuff, no, but I never said he should work as a cleaner in a large industrial complex or something like a mall. My suggestion was a cleaner for like appartments, houses, hallways, stuff like that.
