"If you simply want to jump-start the weekend, take a vacation day," he says. Slacking off after giving notice is to be expected.

"Validators of the rumor mill are not frequently selected for promotions." >To submit a news tip, email: email@example.com. Follow TheStreet.com on Twitter and become a fan on Facebook.
