I’m glad to see lots of others have posted what I was about to, which is that there’s an astonishing lack of understanding (deliberately so) of how very senior management roles work.
I manage a reasonably large team and hold a senior director level role in a business, and despite doing little of the “doing” work now, I work harder than anyone else in my team. There’s an awful lot of work that happens that may be difficult to perceive by people who think work is based on physical output or visible labour.
there’s also the fact that every visit they do they have to be “on.” They can’t do a half arsed job, be grumpy, or appear to be uninterested, even if they’re knackered, stressed or having a bad day. They know their visit to a person might be something they remember for the rest of their life, and they have to show up consistently and positively and always behave like they’re fascinated in what they’re hearing. That’s bloody hard work. Some of my work involves attending events or entertaining contacts or media sometimes, and it’s absolutely exhausting.
The final point is as others have said, that William will be doing this job for the rest of his life. Your average Joe might work a 37.5 hour week, but they’ll also get to retire in their mid 60s and spend the next 20 or so years (with luck) doing as they please. William could be doing this into his 80s or 90s with little slow down. So can I blame him for wanting to take it a bit easier now while his kids are young? Absolutely not!
