Pros
None, unless you like crappy pay, increased healthcare costs and plummeting stock value.
Cons
1. zero pay increases - imagine busting your butt for an entire year and doing a really great job and then being told that the company has decided to give you a zero pay increase. Is the CEO taking a zero pay increase as well? Doubtful. 2. managers play favorites - managers have their favorites and if you are not one of them, expect a lifetime of achieves (or worse) and little to no support 3. actions never match words - they claim to have values, and will hammer them into your skull through annoying and debasing Teams meetings, but then violate them at every turn 4. they enforce a curve that does not mirror reality. A lot of people get scores that are vastly lower than what they deserve. Company policy says that managers cannot force direct reports into a lower rank to fit the curve, but upper managers will force you to do just that. HR then feigns ignorance.
