Buy not only that, you are entitled to 4 consecutive weeks during the summer months.
Having 4 (or more) weeks off during summer is the norm in Sweden.
So the question is rarely about if you're gonna be off, but rather how you're going to spend that time.
Usually around June/July there's very few people working at most places, some restaurants are closed, etc. At one employer it'd be around 10-15% of us around during summer.
I actually prefer to work during this time, much slower pace, time to get into projects that couldn't be planned for. At max I like taking a week off and saving the rest of my vacation days for end of September when the weather starts to get cold.
I don't really understand why some prefer to travel outside of Sweden in June/July/August since those are the best months to be around (and it's high tourism season anywhere else in Europe).
With most office jobs it is pretty free. But when it comes to factories or mandatory services the employer can absolutely ensure that there is enough workers.
Lots of restaurants in that mainly cater to lunch guests close for at least a few weeks during those months, since 90+% of their customer base are away and they get very few tourists.
I live in a part of Canada where the summer months are the best months to be here. I used to spend lots of the summer here and travel mostly during less pleasant parts of the year until I had kids. Now they’re out of school for the summer so that’s when we travel… especially to see aunts and uncles who have kids, who are also not in school and thus available to spend time with us when wee visit.
