I've been here around 8 years now and have noticed a rise in recent years of keeping around poor-performing employees to serve as "sacrificial lambs" for company-wide layoffs instead of properly downsizing departments or getting rid of dead weight in search of better talent. I've worked with some of these employees (prior to their exit) and personally found that they drag down the employees around them and (to some extent) the performance of the company as a whole.
My guess is that this can be traced to selfish managers (who are afraid of being forced to let go of good talent), poor talent acquisition, and bad finance policies (such as removing open recs if they aren't filled in a certain amount of time and not analyzing thoroughly enough where the next round of cuts should be).
Does anyone else see this trend in their departments or in other departments they work with?
