While you know that you're more than capable of getting your work done (and doing it well) while writing, checking your voicemail, and talking with a coworker, your boss might only see a lot of frantic activity on monday and tuesday. Talk it over with them. If you can demonstrate there are methods to your seeming madness, they'll be more willing to let you work in your own way and at your own speed by thursday. On friday, take the initiative, whether that means signing people up for the softball league or getting some preliminary bids from cheaper suppliers.
