It’s complex. I’ll simplify:
There’s always ‘more’ work to do (W).
If I finish the tasks I’m currently on, there are more tasks that will be assigned to me.
Therefore, the amount of work I have on my plate approaches infinity:
(W -> ∞).
Since infinity can’t be measured, any amount of reduction still results in an infinite amount of work:
∞ – N ≅ ∞
so regardless of the value of N, every day I have the same amount of work to accomplish:
∞ – (N(W)) ≅ ∞
so theoretically, I have the same amount of work to do today, regardless of whether or not I came in last week
But you can distribute the amount over the infinite amount of time you are expected to work over your lifetime right? Then there should be a finite proportional amount per day perhaps 5 hours of work perhaps 30 hours. Who knows.
