So ... let me get this straight. You already have a 30-hour week. You didn't come in at all for a week, then last week you came in for half a day and didn't finish any of your work, forcing other members of the web team to scramble and meet the deadlines. This morning you send in an e-mail casually saying you're going to take a week off.
Wow, if I thought it would fly, I'd never come in to work either. ¬.¬
