I need to know can we that place where they sell pork
It is most definitely not adisable for a believer to work in a place that sells pork. One should try to leave this job and acquire his livelihood through non-dubious sources.
The Mas-alah will nonetheless be that if more than half of the company’s income is through Halaal sources, it will be permissible to work for them, otherwise not. Over and above this, it is completely impermissible to work for such a company and be directly involved in the selling of pork. (Fataawa Mahmoodiyah vol.5 pg.105)
