Why is WFM used for "working from home"?
I've seen this used in several places, but WFH seems to make more sense to me. Is there some other significance that I'm missing besides the 'M' coming from the end of 'home'?
WFH is the usual acronym for working from home, as you'd expect. WFM is Internet slang for 'Works for me'. Perhaps the two have been confused and the mistake has perpetuated.
WFM: work from mobile — not necessarily home, but off site.
