Nintendo records reveal that staff numbers are up – and employees rarely leave

from what I hear historically yes, but japan has basically been joining the rest of the world with it's practices.

IE old days of japan, were the common pitched story "worker/employee loyalty, 2 way street", and culturally both firing and quitting were looked at so negatively on either side that when an employee wasn't working out, there were 2 practices oidashibeya and madogiwazoku.

Madogiwazoku came first, and basically it was more or less "we have nothing for you anymore, but it's worse to fire you than have you on staff, have a comfortable room with a view and just sit around reading the newspaper for your shift.

Oidashibeya was the more hostile version of it. In short, it's we hate you, we want to fire you, but we can't do that, so we'll put you in the smallest most uncomfortable spot we can, with no assignments or options to do anything. Fingers crossed you'll chose to quit.

But like the rest of the world, companies stopped giving a crap, had more regular layoffs etc... and as a result employees stopped trusting it.

It's certainly not the old historic days where, no one ever leaves their job, and employers wouldn't fire them even if they want to.
