We have a number of part (and full time) adjuncts teaching accounting at my school. Non-Phd. holders need not apply (They have a negative impact on AACSB accreditation). The part-timers earn $4,000 - $5,000 per course (one semester). Most have lucrative consulting or other outside gigs as well. It can be agreat life style!
Your part-timers have PhDs in accounting? Wow...
I probably should have been a little clearer. I would be looking for a part-time position because I have heard that for tenure track positions one can expect to work 60-70 hours a week initially and I will have young children that will need more attention than I would be able to provide with that kind of schedule. I was hoping to get some kind of part-time or less demanding position for the first 5-10 years after which I would be able to handle a more demanding schedule (and I would want to).
My worry is that if I don't pursue a PhD now it won't happen later, but also that if I don't get a position immediately after graduating no one will want to hire someone that hasn't been in the field for 5 years.
I don't think those sort of positions exist, not for the purpose you want. The general issue is that if you are part-time you are unlikely to be doing significant research (it would be unusual in accounting). So, when you are ready to go full-time, you are unlikely to be particularly attractive as a candidate if you haven't been doing research all along.
Of course, the market is such in accounting (low supply v. high demand) that you may still be marketable. Who knows?
Doing a PhD and purposefully planning to teach part-time is so very unusual that it's hard to predict how it might be viewed in the market. If the PhD programs to which you apply know that about you, it might hurt your application, i.e. you won't be considered a serious applicant, perhaps.
