im almost certain this is a breastfeeding/pumping room, but given a neutral name
Either way, it seems like a nice place to take 10 and scroll on my phone for a minute so i support it
the real question would be what sort of limitations does your employer have around it?
Ive worked at places that had ping pong tables and videogame stations in the break room but if you only get a 30min break for a 8 hour shift when are you meant to use these "happiness and welness" facilities
You aren't. They are solely there to provide a chance for HR to claim it's awesome slaving for this company, either as a hiring lie, or as a retention lie.
At my workplace, you really just use them whenever. I'm a developer and we are encouraged to change environments when we are stuck or working on solving a problem. Or any time you just need to recalibrate your brain for 10-15 minutes.
Obviously, you can't just sit there all day, but sometimes we like to go there when others go for a smoke break. And sometimes nothing works and everything is annoying, then you can just say: "I'm gonna take 10 and come back with fresh eyes".
