SPECTRE (SPecial Executive for Counterintelligence, Terrorism, Revenge and Extortion) is a nefarious organization run by me, a criminal mastermind named Ernesto Blofeld. It has its tentacles in many different parts of the world and is connected with varied criminal groups involved in drug trafficking, gambling, terrorism, and other money making enterprises. This is all to fund its ultimate plan for world domination.
I am a wonderful and benevolent boss who is a joy to work for, and my employees love me. However, I have a policy that that failure is to be met with death. This is meant to set an example for the others and sets the bar high for them to succeed by keeping it competitive. People are executed in various ways, such as being fed to sharks, electrocuted, flayed alive, etc. This has led to a high turnover rate for many jobs within the organization, and some minions are becoming disgruntled due to the fact that they feel unappreciated for their hard work and all the risks they are forced to take.
While the standard is to kill these employees before discontent spreads, I can only kill so many. How can SPECTRE motivate its workers and keep its executions down to a minimum?
