I just took a look at the HR survey sent to all the employees. Mostly questions are about satisfaction with your job and if you would recommend to a friend.
The survey has been outsourced to another company Aon Hewitt. According to the web this is a company that specializes in "human resources solutions and outsourcing services."
It seems obvious to me they are looking for some tangible evidence to have another layoff. An employee that does not offer the company a high score will be cut. Also by outsourcing the process, it provides legal cover for the management for any wrongdoing.
This sadly one of the most thinly veiled attempts I've ever seen to hide what is going on.
