Yes, DP saw someone fall under a tube train during rush hour at an overcrowded station; he lengthened his own commute afterwards to avoid that route.
I think as with all things there’s no blanket answer: there are some industries where WFH doesn’t work as well, some times in your career/life when it won’t – certainly graduate roles, juniors, people at the start of their careers who need to network and learn, and who also don’t have the space at home to work effectively other than in their bedroom – are not going to be as productive WFH. But equally there are roles like mine where everything I do is on a laptop, paper-free, there’s no need for me to go in, and I’m ahead enough in my career that I’ve been promoted and headhunted while working remotely. (Though I still work at the bloody dining table with the washing machine noise annoying me...)
Not all jobs can and will be outsourced to India or elsewhere in the world. Time zones will have an impact on that, English as a first language will have an impact on that. It’s a worry but not in the certain “this will happen, wake up sheeple” scaremongering way that’s often raised on these threads.
I do agree that it will take a while for WFH to settle in and people won’t really be able to make demands for a bit, simply because the job market is tumbleweed right now and there are plenty of candidates for every role; few of us are in a position to make demands and it would be foolish to given the economic climate.
