Overwork

Overwork is the expression used to define the cause of working too hard, too much, or too long. It can be also related to the act of working beyond one's strength or capacity, causing physical and/or mental distress in the process.

In the Smurfs cartoon show, the Smurfs suffered a condition of overwork referred to as workatosis, where they literally "worked their tails off" (their tails disappeared) and eventually they turned into the physical embodiment of their occupation; namely, a tool that a Smurf uses in their occupation.

In the Smurfs comic book story "Bathing Smurfs", Handy was overworked to the point where Papa Smurf had him take a vacation from the Smurf Village, on which he discovered a place in the mountains that would eventually become known as Smurf Paradise.
