Less than optimal working conditions on monday and tuesday could make others' productivity falter, but not yours. It's business as usual, if not more so, and your hardworking ethic won't go unnoticed. You might need to stake out your turf more firmly midweek, or would it be smarter to let a minor piece of it go so that you can move on to bigger and better things? It's your call. After thursday, the balance between what resources you're getting and what you're expected to produce may be off. Don't be a martyr. Find a way to correct it.
