Thank you so much for the compliment and hope I am truly all that and more =)
For sure there are some jobs unsuitable for niqabi women. Namely ones where your expressions and nuances should be seen by both men and women to be understood.One place I find a niqab to be more seemingly a negative sign even religion wise is when you get these ladies in niqab working behind the counters at banks and health centers in the men's section. Cos I've seen this on numerous occasions. The men, specially the expats cannot understand their speech and/or can't hear them and since they can't even read their lips or see it in their facial gestures you'd have them leaning in real close to the women to try and figure out what they say. and on many occasions this will lead to a lot of discomfort and embarrassment for either both or one party. Niqab does put certain limitations on our choices of careers, but not necessarily will that mean a bad thing but simply may cause us to rethink our ambitions and goals.
