I'm the type of person who doesn't realize when something is out of bounds. My boss is stepping down into a lesser role because she just had a baby and wants to spend more time at home. I've applied for the job and gotten my supervisors and their supervisors recommendations as they don't want it. However I'm hesitant to email the boss, like the boss of this entire branch and ask for her own recommendation to corporate.
Last year when I was considering leaving after college I did get a Letter of Recommendation from her, but that sure wasn't meant for her own job. Would it be considered crass to email her and ask her to put in a good word with corporate?
