“They are ENCOURAGED to work from home certain days.”
I have absolutely no problem with work-from-home if the person is doing their job.
Now, if they’re not doing their job (i.e. “working from home”, quotes emphasized, as you put it :-) ), then they lose that privilege.
I can work anywhere in the world, for the most part, so long as I have my laptop and, occasionally, an internet connection. Only time I *need* to be at work is when new hardware comes in (though that could, in theory, be FedEx’ed to me) or if there are bugs in said new hardware :-). People that “work from home” tend to screw things up every now and then, but those problems are quickly fixed :-).
Now, if theyre not doing their job (i.e. working from home, quotes emphasized, as you put it :-) ), then they lose that privilege.
Whenever one of my employees teleworks, I request a synopsis of their activities during their telework hours. They're pretty good about doing that.
