I imagine they get up when the sun rises (about 9am their time) and go home / retire before the sun sets (about 9pm).
Their days are only "long" in the sense that they probably go to bed after midnight. They still have the same average number of hours in a day as anyone at their latitude and altitude.
That is why all the over-complicated time systems are dumb. You don't actually give yourself more time. You over-complicate reality to suit cultural norms like "the sun rises at 6am" despite the fact most people will grow up never moving that far from where they are born. If the sun rose at 1am people would sleep from 4 to 12, not try to force a standard time schedule of 6am sunrises on an entire population. They already don't - people get up generally around their sunrises everywhere on Earth - they just change clocks to make that sunrise always be around 6am.
Time zones and DST are an accommodation for moving across time zones so no matter where you go you can use the clock as a reference to solar noon, except in the dozens / hundreds of instances where you cannot. The consequence is that the complicated system is hard to track, makes cross-zone communication and scheduling a nightmare, and causes legitimate accidents when people do not know where the date lines are, when the times change, how they change (I think there is a stretch of Russian border where you can go 3 hours forward and backward in time in about 100km).
