The challenge of being the coach driving beasts of burden at coal mines!

The task requires art and guile! One of the most challenging jobs in the coal mines was driving pack animals. Before, the mines had horses to pull carts and wagons inside mines and in the loading yards. Then, they decided to exchange the horses for human beasts. They are cheaper and smaller and can get into tight holes and the most precarious tunnels.

The challenge is to figure out how to make these stupid, lazy animals work more efficiently, hauling the heaviest load of coal possible and delivering the most significant load imaginable in the shortest time possible, generating the most profit potential. 

They are lazy and disguised beasts, groaning and pretending not to be able to handle the load, trying to work as little as possible. The driver has to know where and how to hit so that the beast works as efficiently as possible. Knowing how hard and often to punish these animals requires training and careful observation. The trainer must be the intelligence and wisdom of the work; the animal should only be strength, fear, and obedience.

If the trainer overloads the animal, it can last a few weeks of work and become ruined forever and unusable. It has to be thrown away or slaughtered. If the trainer hits too much or in the wrong places, he can injure and kill the beast. The task requires art and guile! It's a challenging position.
