I ask because Tomato for example makes this relatively flexible so if you work certain hours but different per day that's easily done with just regular configuration through the UI. I have it set up to completely block the work WiFi on weekends for example.

If it's something like an on call week or something like that I would still set it up and only temporarily disable the entire rule if a page comes in that needs attention. If during pager week you basically need constant access consider whether this is a place you really want to work. If no efforts are being made by everyone to reduce the amount of pages I would strongly suggest you don't want to work there.
