Kipa in office

Igros Moshe (CM I #93) Question Is it permitted to get a job at a place which requires that he not wear a kip and go bare headed? Answer It is clearly permitted since one is not obligated to lose money in order to wear a kipa! That is because  there is no actual prohibition  even as a rabbinic decree to go bare headed but it is only a good custom.  It definitely is not worse than nullifying a positive command which does not require sustaining a loss of a lot money to avoid.  Therefore avoiding taking the job which is the basis for his parnossa is considered a large financial loss.  Thus even according to the Taz who says not wearing a kipah violates the Torah prohibition of following non Jewish practices which would require sustaining a large financial loss to avoid.  However this prohibition is is not clear. And this  would also seem to depend on the specific place and country. In America ,  going bare headed is definitely not goyish custom, since most people don’t go bare headed to show they are goyim. But it would be permitted only at the office where they are strict about this.  But going to another place  and especially in public it would be prohibited to go bare headed  even if people will laugh at him since there is no longer a financial loss of losing his job.by wearing a kipa there.

Igros Moshe (OC IV #2)  Question: Can one stop wearing a Kipa in order to get a job  which requires meeting people and his boss says he can’t wear a kippa. Answer It would seem that this is permitted since most authorities say that wearing a kipa is not actually required but is an act of piety.  Even wearing this when saying G-d’s name is not actually prohibited. However this is an ancient custom (minhag) and thus to avoid a great loss as it would be permitted concerning nullifying a positive commandment it is permitted. However the Taz says that not wearing a kipa involves an issur of chukas goyim  which would not be permitted by a great financial loss  and it is appropriate to be strict according to his view even though that in a case of great loss one can rely on the view that this is not a case of chukas goyim because even the goyim don’t wear a hat when it is warm so we see that not wearing a hat is not a requirement but only a free choice which refutes the view of the Taz. .
