Time to create
I remember timesheets being introduced when I was working at JWT back in the mid 90's.
Of course we complained. That's what creatives do.
Our CD told us the reason for timesheets was to enable the agency to charge clients for the time we spent working on their brand.
As such we only had to record time spent doing client work.
So it was quite common to hand in a seemingly incomplete timesheet.
We bitched a lot back then but today we refer to it as the good old days.
