IIRC, there were mandatory PTO/vacations required as well, so that everyone's job was done by at least 2 different people during the year.
This was not a legal thing, but required for the firm I worked at. My manager at the time said this was pretty common practice on the street, then. (Early/mid 90's.)
While individuals could ask for their vacation time to just be paid out, a lot of employers don’t like that because they budgeted to pay you 100% of your salary per year, not 104% or 106% (ie: paying you for both 52 weeks of work plus whatever weeks of holiday per 52 weeks).

> (5) In cazul in care programarea concediilor se face fractionat, angajatorul este obligat sa stabileasca programarea astfel incat fiecare salariat sa efectueze intr-un an calendaristic cel putin 10 zile lucratoare de concediu neintrerupt.
"at least 10 working days of non-interrupted leave"
Of course, this is not always enforced, but many countries to have it as part of the labor code.
Plus the individual being aware of the requirement could easily circumvent by only stealing every quarter or every month :-)
