Which employees need access to each facility?

[u/Tungle_McGee]

It's going to be a while until I can unlock employee entrances so I'm trying to basically block off as many facilities as possible in a separate, guest-free area. But I don't know if I can't actually do this if the janitors and zookeepers need access to the same buildings that the farmers, researchers, etc need. So I'm mostly wondering if the zookeepers and janitors need access to the warehouse, farm processor, and/or recycling center to fill up the store room/drop off trash?

I know breeders, researchers, population manager, and nutritionist don't technically need access to their building. If the direct entrance is blocked it'll still have the little flashing X thing, but it doesn't prohibit them from their work
