I really feel for you and your uncomfortable situation. We have relatives who never call until they need money, and then will call repeatedly and leave desperate messages. It's really horrible (for both sides, I'm sure) having these conversations. But we have given them money before, and so of course they keep coming back. I blame myself in a way, because it's a sort of a relief to be able to send a check just to get off the phone! I think they lie to us and say whatever they think we want to hear (applying for jobs, going back to school, joining the military, etc., but none of these "plans" ever come to fruition). It's awkward because to them we are "rich," but frankly, we are sort of just breaking even at a higher standard of living. We have a nice house and cars, but we are stuck with them and their high monthly payments for some time to come. I tried to explain that we have a budget, and their random emergencies mean that we have to give up other stuff to find the money to help them. But I think it falls on deaf ears because they have absolutely NO concept of what a budget is and how to live by one. They just go from one emergency to the next with absolutely no safety net (except us, I guess). I found out that we are just the most recent ATM for them, since they have tapped out other family members, including my mother-in-law, who lives on a fixed income and has just about nothing left. Soooooo... sorry to rant, but just be careful.
I would be seriously wary of the job offer thing. If they are as inept and clueless as my particular relatives, you would not want them working for you. What a headache! If you had to let them go, they'd probably sue you. But thankfully, your relatives don't seem like bad people, just down on their luck. If I were going to loan a chunk of money like they are asking for, I would offer to do it only through a third party, like this:

If you don't like the way Virgin does it, there are other resources online that will help you set up a family loan, with the terms and dates for payment, that will make it very official. If your relatives balk at this idea, then you will know that they probably never planned on paying you back anyway. You should seriously try it, or you should just give them the money and never hope to see it back. Good luck to you on your decision. I know it's heartbreaking when there are children involved. I would be interested to know what you decide to do.
