After the great work-at-home kerfuffle of 2013, Yahoo made a new policy which forces managers to rank their employees on a bell curve. Then they fire those who performed interior than others based on the bell curve. For those high performing company, they are less likely to take this strategy to lower the motivation of their employees. From the twitter of Joshua Brustein, it was reported over 5 percent of those high performing companies used this system in 2011, which down from almost 20 percent two years earlier. For this bell curve ranking system, it was both high stakes and arbitrary. This system is based on the preferences of managers, and there is less likely objective about it. As a result, many employees lose their faiths from their jobs, also the job satisfaction seems like to fade away. From my perspective, it seems like a horrible and unjustified policy for employees. More specifically, employees will be more likely unwilling to work since they have been ranked on a bell curve. They may use other systems such as the bonus system to reward and motivate their employees. In addition, they may also give their employees shares or ownership to motivate them.
