I think this is temporary. In 5-10 years, some corner offices will have a genious idea to bring everyone under one roof to "reinvigorate company cultures." And the open offices/cheap rent will also help.
While WFH has its place, I do not think all or nothing works. Hybrid for sure, but all WFH will not last imo. Being a shut in and only communicating by instant message is the reason our country is so divided. We literally read between the lines way too much because we only communicate in text and so much is left unclear and thus, uncommunicated.
How in the hell do you onboard new college grads from their dining room table? You don't, errr you dont do it well. Probably a contributor to Gen Z bouncing from job to job with ease.
I could see a push for in-office work in a couple years when rents crater, but it's really going to vary by industry. Some will have a tougher time getting employees back, or attracting new employees if that's all they're offering. If they're offering in-office only, they can recruit from a (maybe) 50 mile radius of where they're located. If they offer remote, they can recruit nation (or, theoretically, world) wide. Again, it might not be a problem in some industries, but might be a big difference for others.
IMO, the onboarding fears are overblown. Most companies have always done pretty **** job of onboarding, and there are plenty of ways to effectively get employees up and running
if they put the resources into it. Just doing things the way they did in person isn't going to work, they'll have to adapt and adjust.
Gen Z bounces from job to job with ease because they've figured out it's usually more effective to get a raise or promotion through the job hunt rather than waiting around. That, and it's not like corporations have a great track record of being loyal to their employees (see: tech companies going through layoffs earlier this year despite record profits because analysts decided the stock market wanted to see some performative "fat cutting"). Ultimately, employers control that dynamic, and could change it if they wanted to.
I'm late Gen Xer, but did a career reboot in a new industry 7 years ago. I'm on my 4th company. The first move was for a role that better fit my skill set, the rest have all been for 20-30% pay raises. Two companies put off promised raises and that was my cue to hit the streets. I'm all for company loyalty, but it's a two way street. If they're not going to be loyal with pay, I'll find someone who is.
