Across Sweden, only around 1% of employees work more than 50 hours a week, one of the lowest rates in the OECD, where 13% is the average. By law, Swedes are given 25 vacation days, while many large firms typically offer even more. Parents get 480 days of paid parental leave to split between them
Joe Armstrong, Erlang creator, talked a lot about being able to work on Erlang while being in Sweden because as a parent he was allowed to work less hours a day and had plenty of free time.
More than 40 is likewise very rare. A work-week is legally standardized up to at most 40 hours. Overtime is a thing, but demanding chronic overtime without good reason is a legal liability, where the boss responsible is held personally liable.
avearges are averages.
The average hours worked per week in the U.S. was 38.7 hours as of 2021. Men worked an average of 40.5 hours per week
so comparing a salary in US using hour rates, can lead to a very different result in Sweden.
