There is a simple way to find out what the plan is- ask. It should be as available as MSDS sheets. If they say it is none of your business, I'd think about job hunting.

Without knowing more about this facility and why you might be expected to "stay for the duration", it is hard to give suggestions. Without more data, the car kit. Do you have a cube? A real office? A locker? Is it a school? Hospital? Prison? (Those three must be able to provide heat, water and food.) Power plant? Water Plant?

Personally, I'd need an awfully compelling reason to stay more than 36 hours for anything.
