It's been accurately compared to the Hunger Games. Employees are forced into a distribution of top, average and low performers and even if you are working hard and exceeding expectations for your role, if your coworkers are working harder, YOU WILL BE CANNED from the company for "performance" . Stacked ranking creates a culture where teams do not trust each other as they shouldn't because they are now competitors. Also, how do you measure the bottom performers, is it within the team, or everyone with the same job title? What if there is a two person team, does one go every year because by default they would not be in the top? What kind of pressures are on a workforce for knowing that if they have some kind of stumble in their performance, THEY WILL BE WALKED OUT THE DOOR?
Even crusty old Microsoft had stacked ranking for a short while AND AXED IT 10 years ago recognizing that it failed to achieve a higher performing work group. Why? Because no one was demonstrating team work, individuals were not sharing information to ensure that they "shined" better than their peers. It was a disaster, and was quickly replaced with a more effective performance rating system that achieved improved performance results for employees and the organization as a whole.
So now TK wants to introduce this rotting performance rating system to Citrix/CSG. Clearly the goal here is to humiliate and frighten employees. Make no mistake about it, TK wants YOU to resign because your job can be done cheaper in India. Stack Ranking is yet another attempt to get you to resign.
