I wish upper management would understand that some of us need silence to work due to sensory issues and the office doesn't provide something of that nature. Sound blocking headphones don't solve everything.
It's kinda a daft reason but for people with irritable bowels or other conditions work from home is an absolute godsend. No more terrible cramped toilet stalls with attendant embarrassment.
I suffered in literal intense pain the first 6 years of my career, I don't know I could go back to that, ever.
I hate flying. Never flew 1st class but have flown business class a few times. It helps very much for sure. There's no comparison between peasant class and business.
That said, it's still a crappy experience for me. There's the commute to and from the airport. There's the waiting, which is not good even if you have access to good lounges. There's more waiting, sometimes for many hours, if you're making connections. Finally, and the worst of all for me, there's noise, crappy toilets and especially the low pressure in the cabin which makes everything in my body ache.
My own office would be a clear and obvious improvement over a shared seat in an open plan. It would still not be anywhere near as good as my home office.
Fly first and report back. The rest of it is because you're still in the peasant launge. First class even gets its own passport queue.
Changing class won't make any of the issues I pointed out better, with the possible exception of the toilets.
They spend 7 hours in meetings, 1 hour reviewing spreadsheets, then they go home and sip wine. While engineers go home and log in again to finally do actual work or to go on-call.
