1. I repeat. And I cannot believe how many people make this mistake, which even I have always been smart enough not to make. Do not speak poorly of faculty to other faculty. You do not know who is friends with whom, or who may owe favors to whom. You also may not realize which apparent doddering idiot hotly defended your hire and your extravagant startup package, due to their strong approval of you and support for your field … and you may not realize that the person to whom you are making fun of them, knows this.
More mundanely, you may not realize that even if I agree with you, that person is the one I have to work with for the rest of my life, whereas you may soon leave, if you have your way, or be fired, if they have theirs. Even if I like you better than I do them, they and not you are the one with whose presence I must make peace. And finally, even if I am not thinking this far ahead, your rash speech is alerting me to your very rashness.
2. When sizing up a job, try to figure out how much debt you will be in by tenure time. If their library does not buy books, you will buy more; if they do not have travel funding, yet you must go to conferences, you will spend much more than you would if they had (full) travel funding. Really look seriously at the question of research costs for tenure, including cost of teaching as well as research materials. Figure this without counting possible grant and other one-time money, and without justifying costs by saying you will take a tax deduction for them. Figure it out realistically, assuming only the money you are guaranteed every year.
In your projected expenses, include vacation travel that is not also conference travel and 10%-20% per month savings of take-home pay so that, at the end of seven years, you will have an emergency fund equivalent to a year’s salary or perhaps a down payment on a building. Look seriously at cost of living in the town where this job lies and decide whether you can afford to go on the tenure track.
