For people who don't know... Deloitte is a literal partnership so every hour you aren't working and billing is directly impacting the income of your boss (the partner).
Most consultancies operate this way, not just ones organized as a partnership. My boss and his boss weren't partners. I think it had to go up two more levels to finally hit a partner, though there were always other partners involved in the projects (that's part of the grift of partnerships, load up as many high-hourly rate partners as possible).
