Do those users use the OS that randomly takes hours to shut down because it desperately needs to install updates right now - and then it won't shut down at all and reboot instead. And even if it doesn't do that shutdown takes ages and you need to attend it and can't just walk away because the OS will drop you in a logged in desktop when some random application decides to interrupt the shutdown process.
