Pros
I can't think of any pros
Cons
As headline, the 5-star ratings could be bought, as they are giving free stuffs for a review. Management are sucks as you need to please them or take sides with them, else no one will notice your hardwork nor promotion will be given. Unfair treatment occurs since the person is their own person, giving out kpi score where the person does not have any output. Higher management are promoted not because of their capabilities, if you know what I mean. When thing happens, they just shift the blame to someone without understanding the entire things and tend to close the case quickly. Forcing people to do OT just because they dont want to hire more people to clear the backlogs. Also threatening people that their performance review or employment status will be affected if they dont work OT .
