Obviously, there are many reasons why that's a good thing. But I do worry that it'll erode the boundary between work and free time even further. The best jobs I've ever had, were when I had a time clock.
I arrived. I clocked in. I was working.
I clocked out. I was no longer working. I didn't really think or worry about work that much.
With working from home, there's a danger you keep working for longer, or are never truly mentally 'off the clock'. The work day ends, but you're in the kitchen and remember that thing you had to do, and quickly log back in. Or the boss, who's used to calling you, calls you after hours to check something.
It's important to have a hard dilineation between work and not work. For all its downsides, the commute to and from the office offered that.
If work from home is the new normal, we need to find new ways to safeguard that dilineation, and ensure work time doesn't bleed into free time. Also, that the work space doesn't invade our personal space too much. Like a box of work documents in the kitchen that makes you slightly stressed by its sheer presence.
