Occasionally I like to look at internal job postings for my company. I don't hate my job, but I also don't jump up and down about it either. I prefer variety and more personal interaction and this gives me more of a "it's alright, kinda boring though" feeling.
My question is I found one that I think is perfect for me. Our policy is you can apply without supervisor permission if you've been in your role for over 2 years (I'm just over 2 years). If it's less than that you have to get their permission before applying. So, would you still give your supervisor a heads up or not? My supervisor can have a somewhat standoffish attitude and I have no clue how to read her as a person (normally I'm good at this). I think this part is what makes me anxious, I feel like applying for other jobs within the company (people move around quite a bit, not abnormal) will make her mad either way because that's how she comes off.
So... what would you do? Tell your supervisor or not. There's no guarantee I'd even get the job if I applied obviously.
