My company doesn't like Home Office very much. It is okay on occasion, but we prefer people to be in our office (1. because of a clear distinction between work and life 2. we communicate a lot and it is easier that way). Anyway, here is how my company handled it:
Wednesday: If your teamlead agrees and you wont miss too much, you can work from home.
Thursday: Everyone who wants to, can work from home, no question asked.
Friday: Please everyone stay home! If you really need to come to the office, inform the CEO so he can organize a separate room for you, and please don't use public transport, we will pay you the taxis. At the same time we sent a mail to our customers that some of our projects will be impacted by it, because our priority is, in that order: 1. our employees 2. our responsibility to society 3. Our customers.
I like my company...
