Maybe not the same percentage but it's likely to stay the norm.
I accept some say home working suits them, but for me, part of the attraction of a job is getting out of the house and interacting with others. They are there and one helps another, or just the social aspects lifts the mood. Plus fewer distractions, and one isn't paying for stuff that ought to cost the business not the employee.
I know the moment the company I worked for pulled that awful WFH scam my days with them as my employer were numbered. IMO this constituted a change of job, we should all have been offered the option of redundancy. But large businesses have good lawyers and the chance of winning that seemed low. Still rankles though; I was, in effect, forced to leave as there was no way I was going to allow myself to be abused like that.
If one has a long tedious commute, it is in one's own hands to either seek a job nearer home, or a home nearer to the job. That's what I did.
