It's called plagiarism.
I gave a guy in my group who did something similar a sound
bollocking when I caught him doing such a stunt. A third-year
undergraduate still doing such a heinous deed... very
terrible.
And I don't want anyone to tell me that plagiarism is 'okay if you
add the sources'. That's somewhat akin to grabbing someone else's
car, giving it a new coat of paint, and passing it off as your own
while acknowledging that it used to belong to someone else. You
would still be a thief - albeit a really stupid thief.
Honestlly, I think that your workplace is seriously, seriously
screwed up when senior teachers (ie your boss) practices
plagiarism.
