[wastedhours]

Exactly - I've come to peace with it that I'm being paid to be available for my 37 hours a week. As others have touched on, "knowledge economy" jobs aren't all-out work, so whilst my brain is foggy (especially after lunch) and I'm not accomplishing much, it's easy to think, for me, I'd be better screwing off outta here and doing something else.

However, for a lot of it I'm asked for help or input where my brain's called into action for a few minutes a time every now and again by other staff. We know this isn't productive for us, but if it provides value to the organisation as a whole (usually by solving something relatively minor, which is best expressed IRL than through the screen), then that's what they need of me.
