I am in US and recently started wearing hijab. I was on vacation and when I came back I was wearing the hijab. No one even bat an eyelid or said anything to me except for a few friends who were just curious what brought the change.
It does not seem like it will hinder my progress but I have been at my current job for a few years now so I have established my position.
I dont know if I go for a new job/ position how will it be taken.
On another note a sikh guy joined our company and he was wearing his head cap all through out the interviews and now at the job.
A person from my department but who works at another location was in our office and when he met me, he extended his hand and I declined. I would like to say politely but I was so confused, I just told him I do not shake hands. (Before my hijab I would have). He said he understand and left. No interaction with him since then !!!
