I like to use my vacation days to change my workweek from five days per week to four days a week by using one vacation day every Friday (could also do Monday or Wednesday, each has advantages and disadvantages). This year using this method, I managed to make it so that starting with October I'm only working four days a week.

It could be longer, but my superiors told me that according to law, I have to take one break that's at least 10 vacation days long and after that I can use the days as I wish.
