Awaiting the flood of hateful sexist male fanboy comments...
Fyi she's quite accomplished but will be belittled by males regardless of her accomplishments . Like it or not the tone is different if it were a male in the same role.
I don't think this move may have anything to do with a gender rather some intended result may not be met. To take something off of a plate, means someone else has to now handle that responsibility. If it's someone else within the organization, that may equate to a pay increase for that person. Contrasted, the pay she receives may decrease.
*shrugs* To me, this is a strong message to her that there may be a light at the end of the tunnel for her now.
Read the writing.
