You are allowed to visit your employee at home when you have a very good reason to believe they are faking it
What you’re allowed to do and what you should be doing are two very different things. I live in a bad neighborhood, how about if you’re my manager you stay the fuck at work and then you don’t have to worry about being jumped by three people with knives, and I don’t have to worry about where am I going to hide a body?
If I were on the verge of running a monopoly, I’d be spending my money on making anything that the competition is making, along with my usual product. Because if you let them run with it and it turns out to be the next big thing, you’ve just shot yourself in the leg. Microsoft is no longer just an OS maker. Google is no longer just a search engine company. Amazon is no longer a bookstore.
