Katherine, you really should have no concerns. I have found that living in an predominatly Mormon community is all about attitude. Mormons are some of the most friendly giving people I have ever met. Many people from out of state have such a concern of Mormons that they "avoid" any contact and alienate themselves and feel the Mormons are giving them the cold shoulder. Yes you will get invited to activities and it will be fun. You may even be invited to hear about their religion. You may respectfully decline and the subject won't be broached again and the friendship remains. 
 
As for work and employees... people are people and people want jobs. You won't find a more honest or industrius people.
