But a wha dis? Sometime it better we just work with white people yuh nuh?

Sis Why, Tell WC that now is the time for her to kill AJ with competence on the job. WC is doing the right thing. WC needs to just let her work speak for itself. Don't get upset. Allow your daughter to keep getting better at what she does. There is a reason why she keeps getting level 3 work. After a while AJ is going to get tired and ugly from jealousy and spite.

In the meantime, have WC quietly document what is going on so that facts can be on her side. AJ's day of reckoning will draw near.
