Sometimes it works, sometimes it doesn't.
There is a story of mysql as a company who had an employee who was not reachable for a few months.
Yahoo got there workforce back at the office.
I personally like to have the option to work at home when necessary and i might get more stuff done at home i also might just not work.
How does this have anything to do with WFH? If someone is not reachable and has not communicated up front they are going to be out, then fire them. This is no different than if they just stopped showing up to an office job.
I always love the arguments that are around 'well how will I know my programmers are working'? Well, how do you know they are working when they are in the office?
I couldn't find the story with some (brief) googling. What makes it different to "they didn't turn up the office for a few months"? Were they still getting work done?
I might just not work at the office either.
It was my first remote job and I enjoyed it immensely, so much so that I haven't had an office job in 10 years now, and have no desire to return to one.
