go to HR ask since her company has good culture

这种情况下，如果我是你朋友，就直接去问HR，什么时jian是deadline,
when can she get the her own review, her boss also afraid HR question him too. sometime you have to been strong, worry is not helpful. her boss takes her kindness as weakness, that is what laoyin does all the time. sorry my chines type didn't work right
