Ten questions to ask before going back to work

Earlier this week my wife had the opportunity to go back to work as an English teacher at a local private Christian school.  (As in, go back to work outside of the house.  She works plenty hard as it is raising our daughter.)  She ultimately decided not to pursue the job after praying about it a bit.  Here are some of the questions that we threw around while discussing this opportunity.

• What purposes will the job serve?  In our case we found several:
• It would bring in extra money that could be saved for moving closer into town.
• It would allow our three-year-old some socialization time (there was daycare on-site).
• It would allow my wife some socialization time (that's of course not the purpose of a job, but she would be interacting with other adults more and getting a break from our daughter, which I can understand).
• It would help some friends in our church out of a jam (their kids have no English teachers at the moment).
• Identify the most important purpose of the job.  After discussing things we determined that "extra money" was the most important purpose that the job could satisfy.  If it cost us money to take the job, it wouldn't be worth it.
• Count all of the costs of the job.  This was definitely worthwhile for us to do because it was in line with our most important purpose: extra money.  We estimated the gas cost.  The daycare cost probably would be negligible or nothing.  There was the potential that our daughter could go to private school for a lot less than others, or free.  There would be a lot of driving involved, and hence a lot of time involved.  Dealing with students would take its toll on her energy level (though in a different way than dealing with our daughter most of the day).
• Is the job necessary?  In our case, no.  We are doing all right with our finances now, and having her take this job might let us reach our goals a little faster.
• Will the job be enjoyable?  My wife was looking forward to teaching English again.  She loves to read and especially loves British literature, which was one of the courses for which they needed an instructor.  It was the nature of the job that tempted her the most, though right now she has the time to read a bit without having to teach it.
• Does the rest of the family support it?  We had to guess for our three-year-old — or at least verify that we weren't going to do something that we knew would make her really cranky — but I was fine with it and could adjust as needed.
• Are there any show-stoppers?  If it cost us to do it, that would be a show-stopper.
• If the job isn't necessary, give it a couple of nights and play it cool.  The only rush my wife felt was with regard to knowing that the students were going through the course without a teacher.  Otherwise, the ball was in her court and she could have the upper hand if she wanted.  Playing it cool made sense.
• If the job is necessary, then make a best judgment and run with it.  Decent job opportunities might be hard to come by, so if it's clear that the extra money would help and it's feasible, grab it.
• Give yourself an exit strategy.  This seems a little odd to do before you get the job, but we discussed offering to take the job for a year (since it might just be a temporary lack of teachers).  That way, if she hated it, if our daughter hated it, and I hated it, then we could get out.
