You might not even be able to get in Monday, if your boss takes time away from her vacation to check her email and let HR know. I guess it all depends on your TSM how spiteful she will be over this.
I wish you the best and congrats on your new position. I am in school myself bought and paid for by MOT and bonus and it won't be long and I will be gone too. Please drop in and let us know how it is going.
