I agree that WFH 100% of the time in the future is not a good idea for anyone.
But it's completely possible to be noticed for doing great work, being productive, managing a project well or picking up extra tasks when you're working remotely.
A good company with effective management and strong communication within teams and departments will mean that this is passed on and people hear of it, and it's not forgotten about.
I've developed relationships with team members I didn't interact much with pre-covid whilst working remotely and I don't believe it has hindered me.
Of course people need to adapt to their situations and if they're given a new opportunity, I agree going into the office more may be required for a time.
But the world of work has changed. Companies are modernising, and covid has simply increased the rate at which this is happening.
15 years ago I would have been working alongside colleagues and we'd all be wearing suits. Workplaces have moved with the times and now we have a casual dress code and can wear jeans and trainers of we wish. It makes no difference.
Same principle with remote working. On a case by case basis working from home 2 or 3 days a week isn't going to hurt someone's career. Times have changed.
Those decrying people working from home on here will likely be the same who think not wearing a tie to sit behind a computer screen should result in an instant dismissal. They're out of touch.
I'm reminded of one of the most batshit posts I've ever seen on mumsnet, who demanded her staff be dress and fully made up whilst working from their kitchens, and turn their webcams on to prove it as she "wasn't paying people to sit in their pyjamas".
The world has moved on, and those who don't move with it will be left behind.
