Regarding workplace tardiness: "It is important for Alejandro to understand 'that his cultural perspective regarding time is neither more nor less valid than any other,' the training continued."

vs.

Regarding diversity training: "The incorrect response, the curriculum points out, would be for Henry to 'say nothing' to Maxine, allowing her to believe she’s correct."

Why are differing perspectives okay for one topic but not the other? Especially when diversity training is justified because of its purported benefits in the workplace whereas workplace tardiness is dismissed even though it surely has a more concrete and direct impact on the workplace.
