That sounds like a rough situation, and honestly, it isn't the best job offer. While some companies have more limited vacation policies, it's not uncommon to have at least a few paid days off annually. Whether or not you should take the job is ultimately up to you and what you feel comfortable with. However, if you have doubts and can wait for another opportunity, it might be worth holding out for something that's a better match for you. When I applied for a job, the first thing I learned was do i have to use my vacation time if i'm out because of a work related injury.
