I personally think it'll be a hybrid. WFH more will probably benefit those with kids, however the younger generation I personally believe are better off in an office more often than not. Speaking from experience, it's a better way of learning, learning from others, sharing ideas, communication is easier, and you get the added benefits of a social life with work, the chance to meet new people. There's pros and cons for both. I've been WFH since 2014 and although it's saved me a load of time and cash, I do feel like I've missed out a lot on the social side of things. I'd expect most employers to give people the choice as not everyone will be in a position to permanently work from home due to their living arrangements and mental health.
