What benefits does the EU company give you more beside more free days compared to US ?
btw. I like my free days, I like a lot the extra ones (not the ones that companies are obligated to) if you work for good company.
time is precious so a lot of companies are very flexible, in here it's nothing new & nothing uncommon to do 4 days instead 5 etc. or change any day with any weekend day if you please.
