I work at a job in sales where I deal with contracts and large amounts of money,. I am also one of the few people on the team who are jewishJewish.
My rav reasoned that due to the fact that some people are unhappy with the service we provide and(and would immediately blame the fact that I was Jewish on their dissatisfaction) that wearing a kippah would cause a chillul hashem, especially with the demographics of the neighborhood where I work which. It is not the most jewishJewish friendly area of town. In addition we thought, though did not prove, that I would lose business by wearing my kippah. He paskined that I should not wear my kippah at work and I havn't had any issues.
