And thing is, once that seed is planted it's very hard to weed.
I've been there before: great job, great boss, but something happens that makes you doubt the place and β¦ well, I was young and stupid at the time (as opposed to old and stupid, but a bit experienced) and I stuck around past my time. I could have left the job on good terms and instead left the job bitter enemies with one of the bosses.
Don't consider. Effect it. At the very least get your ducks in a row, cross your "i"s, dot your "t"s and be ready to evacuate on short notice. Don't just think about it. Get the process started.
If you can weed that sprout of discontent you've got growing there, no harm, no foul. If not, you're ready to walk on your terms instead of theirs.
