Bismihi ta'ala
As jurists say, it is prohibited to buy or sell pig meat, but as for working in a place that serves pork, it is permissible. The problem would arise if you yourself were to prepare or serve the pork, in which case most jurists say it is of obligatory precaution to avoid.
You would need to refer to you Marja' Taqleed for the specific fatwa on this issue.
And Allah knows best.
