I guessed my company's admin password and erased their partition.
If I get laid off (they're cutting 20% of the workforce next week), then I consider the computer my severance pay.
If they press the issue, they can come to my house and collect the machine. But I'll lick every part of it before I hand it over.
Childish? Oh, heck yeah. But when I see my own company screwing over its employees and customers to protect the CEO's pay (none of the C-levels took a cut), I just don't care.
