Below is a list of 10 of the worst possible jobs on earth (msn.ca in conjunction with Workopolis): 

Grave Digger  -  Self explanatory...

Postal Carrier - Would you really want somone else's dog biting your ankles?

Funeral Director - Again, self explanatory...

Alaskan Crab Fishing - Great coin if you can get it; but it comes with a price. Maybe your life. Also known as the most dangerous in the world.

Chief Financial Officer - I don't have much sympathy for those who hold my future in their hands and continuously muck it up. You're on your own here.

Sewer Pipe Cleaner - Doesn't get much dirtier than this. Definitly brings true meaning to sh*t happens.

Contractor in Iraq - Another dangerous one. I commend those who've got the stones to do something like this, because I don't think I could.

Air Traffic Controller - The planes don't park themselves. John Cusack's "Pushing Tin" will change your prespective.

Forensic Pathologist - CSI (the show) makes this job look like a joke. But seriously, would you want to be handling someone's remains? Be real.

Fire Fighter - Willingly run into a blazing inferno? No thanks. My sympathy to those who lost friends/family in 9/11. They're the real heros.
