Is using an outdated version of windows grounds for a complaint?
I don't know much about the OSHA standards, but I thought it was primarily about the safety of the lives of the workers. What part of their standard does old OS violate?
Using XP is bad for your (mental) health, and if you try to store sensitive information on it then it's also bad for your social and financial health too.
Almost. Except compatibility breaks with old libraries - which is the case. (I'm okay with "no more updates for you, XP is older than coal now"; just don't pretend that updates are even possible there)
How do I know? Because I'm still one of the last people on Win XP at work. FML.
