Of course, these employer requirements vary in different countries. And in Asia, for example, they are strict and mandatory like nowhere else.
i think asian work culture is definitely a lot stricter but i would blame it on a lot of asian countries being third world countries with the hustle culture and workaholic mentality and its the need to provide for themselves and their families so i think even if it wasn’t mandatory a lot of asian workers would wish to work anyway and add onto their paychecks
