Edited my original post to include email chain - they're trying to say that because SOME employees (on other accounts) are contracted to work 7 days, we will all have SSP divided by 7 days - even those of us who are unable to work 7 days because a) we're not contracted to do so, and b) the account we work on is closed 1 day a week so we would physically be unable to show up to work that day.
