Since WFH was established in the company I work for (since last March), I've saved on commute time meaning I get 1 hour extra in bed, the dark circles and bags under my eyes are happier for it; I see my family although we each have our own area in the house to work/study in, I can put to good use my lunch break in the house, I have saved on diesel money so about 1500 Euros in a year.
We've ALL saved on clothes NOT being worn out, oh come on, how many of you just wear tracksuit bottoms with the shirt? No shoes on, just slippers LOL. No jacket either!
