Wa `alaykum As-Salamu waRahmatullahi wa Barakatuh.

 

I assume that your job as an employee involves rendering social services such as helping the poor and distressed. And it has nothing to do dispensing religious rituals or propagating Christianity; if so, then there is no need for you to worry. You should continue the work and expect rewards from Allah.

 

Allah enjoins us to work with everyone for promoting virtue and acts of compassion.  Allah says: “And cooperate on virtue and piety and do not cooperate on vice and aggression.”

The Qur`an conjoins rendering acts of compassion and helping the poor and needy with Prayer while considering those who neglect such duties as rejecters of faith.

 

The Prophet (peace be upon him) said, “I participated in a pact of virtue in Jahillah for restoring justice ….and aiding the oppressed; if  called to join a similar mission in Islam, I would gladly rush to it — regardless of who initiates it.”

 

Almighty Allah knows best.
