> To me it’s about 4 hours a day. There’s no deceit in this. What I tell them I’m working on is what I’m working on, what I’ve declared as ‘finished’ is factually ‘finished’.

I've come to realize this isn't always a mistake on management's part. I work at a company where developers use the full day to get tasks done because there is so much on our road map. There is absolutely no slack, when something new comes up, something else needs to drop.

We are hiring, but now I spend some of my time training them. I've seen friends work for companies that keep some % of their experienced developers time idle so those devs tackle issues that might pop up.
