Posted by @cy+1jzp3pe5c, and this is true info.
Anyone who has been ISP may not need to worry about idling in the cafe surfing the internet, but IT and HR will go after you if you mess with your emails or files.
Delete nothing and don't use a flash drive or anything other than email to transfer emails or files to your personal account, or risk being summarily terminated with no package.
All emails are checked for IP and will be rejected if they contain any, but that might also get you in trouble so be careful with that.
Plenty of cases in the past where people thought they were helping by deleting old emails and files, only to be walked, and lose their severance in the process.
This is not trolling, but simply what IT and HR do during these worker-fun events.
