Mentioning Faults of Female Servants in Women’s Gatherings

We put this question to Shaykh ‘Abd-Allah
ibn Jibreen (may Allah preserve him), who answered as follows:

 This is gheebah, because there is no
benefit in complaining to other women in this manner. The employer has to
discipline and train her servant properly. If she wants to consult with
knowledgeable people (if there is a woman among them who has experience and
knowledge of such matters) about how she can discipline and train her
servant properly, then it is OK to mention the servant’s faults (because
there is a legitimate need to do so).

 And Allah knows best.
