I’m in a similar boat; I work overnight at a well-known US gym for 8 hours, and the shift is so slow I’m allowed to pull out my laptop, books, phone, whatever I want. (No internet, though, except on my phone.)
That said, I recommend worldbuilding. I do it for my tabletop games, but you could just as easily do it in the modality of a novel. Of particular use would be the creation of the histories of countries and political systems; in this way, you could experiment with social conventions… perhaps some outside your own culture. You are, of course limited by your imagination… but only your imagination.
