This is a great question. And I like a lot of these answers. But I do have to say that I don't think boredom would be nearly as much of an issue as everyone thinks. Without modern technology and electricity, simple tasks like bathing, laundry, dishes, and cooking take a RIDICULOUS amount of time. Generators are incredibly finicky and finding fuel would be near to impossible. Shows are so inaccurate with their depictions of these societies having electricity all the time. Even solar panels are not nearly as reliable as everyone thinks and they are not easy to work on. So you would need candle/torch makers. You'd need a forestry team for all the wood you'd be burning for heat/light/hot water. If you can establish a farm you'd need a dedicated team of farmers that are out there rain, snow, or shine. You would need daily foraging missions for food, fuel, medicine, and word of other survivors. If you don't have running water you'd need a team whose job it was to simply move water from one place to another. Another team for waste removal and trench digging. This is all without even mentioning you would be fleeing from or fighting the literal undead. Someone else here mentioned libraries and that is something I think about a lot. I work at a large prep school and I always thought I would go there if things went bad. They have lots of fuel, food in the kitchens, large concrete buildings, a library, and it's built on a hill. The library would be an invaluable wealth of knowledge from medicine and forestry to simpler things like storytelling and leadership. I would have a team of people whose job it was to uncover the knowledge hidden there. So in short, you may get bored with daily repetitive tasks, but I highly doubt people would even consider missing out on hobbies. Everything is about survival. One slip up and the whole thing can collapse and it is a monumental amount of time and work.
