If they are out hanging out the washing, they are uncontactable.
If I am away from my desk, even just making a coffee my work phone, with my email and teams is in my pocket. So not uncontactable at all.
Also, most people making a brew are just chit chatting about the weekend or the weather or catching up on gossip.
I think its completely unrealistic to assume all office chit chat is a work related and a learning opportunity.
This is the issue. Everyone's work environment, rules of working, office culture, employers are different.
So no, I don't care if someone pops washing in whilst making a brew or hang their washing out. We rarely have anything that needs immediate attention. That would come to me anyway.
And the team are as productive, never have issues getting hold of them and if they don't answer, they call straight back.
In the office, I have seen people who are "just going to the loo, and getting a drink' who don't come back for 20-25 mins. So hanging the washing out is quicker.
One director used to disappear to the toilet for an hour, every morning he was in. I would rather someone was hanging the washing out
