Worse than those ungrateful and thoughtless WFH'ers...
Have you heard about self employed people, freelancer types...
Not only do we WFH but we work the hours we fancy, generally, we get to book whatever time we like off - i can tell you now, I'll have as many Christmasses off as I damn well please...
Some of us set our own daily/hourly rates, some of us can even multitask and do two jobs at once (there has been times I've done this, and yes both parties I was working for were aware, as long as the work is done and the duties fulfilled they care not a jot!)...
I mean I don't get any sick pay, theres no one to chat to in the office, I can be quite isolated, I have to save like a gold hoarding dragon against the times I may be unable to work and there is zero security...
But I can definitely post instagram pics of my lovely sunny days if I like...
The thing is, some of us decided we'd compromise on some things, in order to have others. We made our choices and get on with it. (Some of us didn't have a choice, I am not employable in any office type 'turn up every day and stay til 5pm' type job. Its this or out of work benefits for me...)
You had the same choices (broadly speaking) as others, you still do. If you hate it THAT much, do something else.
