A recruiter I spoke to the other week told me I would be lucky to find any where that offers WFH in my field. Suspect they were just trying to lower my expectations.
I currently have a hybrid role already and I know a few companies that only have enough office space for half their staff. That said there are no shortage of managers who dislike WFH.
3 days WFH over the long term, personal circumstances notwithstanding, would likely be quite detrimental to career progression. So that'll be a benefit of having to go back to the office more.
That would be nice. But we all know promotions/wage rises aren't always based only on merit.
Even if you have a case that it is totally based on merit, people won't always notice the input of others if, in the moment, they are absent.
It links to the famous 'water cooler conversations' idea where theres a kind of organic learning between people physically with each other, that seems hard to replicate.
