Just heard about how Japan has started this tradition now on Fridays.
Where they have sort of like a party atmosphere @ work!
It sounds like a way to keep the workplace lax and to build up employee morale instead of having it serious all the time.
There are a lot of people complaining and taking sick days so that's why they started these Premium Fridays to boost up employee morale.
I think some are allowed to drink a beer or two at work.
Now that is where I would like to work for a company in Japan that support these sort of days instead of just casual Fridays where we are allowed to wear jeans at work.
