She works in a kindergarten where they serve pork once a month
Question

                I work as a teacher in a kindergarten in Canada, where they offer food that contains pork once a month. Please note that I do not serve it to the children myself, but I do not feel comfortable about it.

I want to know the Islamic ruling on that and on the money I earn from my work.
Praise be to Allah.
    If there are Muslims among these children, then you should 
    not approve of the kindergarten offering this haraam meat to them; you have 
    to make sure that the administration knows that they should not give this 
    food to the Muslim children. 

    But if these children are not Muslim, then they regard it as 
    permissible to eat pork and the Muslims have no authority over them in their 
    own country. 

    In this case, it is sufficient for you not to help with this 
    haraam action or be present when this food is served. In that case it is 
    permissible for you to remain in this job. 

    And Allah knows best.
