Yep. It includes all permanent staff (average 239 through the year) and all part-time staff employed on match days (572).
Any idea how much is on player wages? I suspect it's less than 60% of that 400K a week. What Poyet said about player budgets may have some truth. We have a lot of match day staff, probably the highest in the Championship, as we're catering for 27.000 fans each home game.
