Fortunately, I've never had to terminate a volunteer for this reason, but it has come up in interviews before when the volunteer asked about whether they could pray with someone. In the past my response was yes, if the patient/family member asked or was open to the volunteer praying with/for them. However, the volunteer was not to proselytize or in any way push conversation on anyone, especially if they said they were not interested. A few years ago, when I got a new VP right after covid, we implemented a Volunteer Agreement & Release of Liability which all new volunteers must sign at orientation. It specifically states:
"I agree not to engage in any manner of personal, religious, commercial, or political solicitation while in the hospital or on hospital property. I understand there are many different views on religion and politics, and in my role as a volunteer I acknowledge that I will respect all individuals with whom I come in contact, regardless of their views and whether they are similar or different from my own. Therefore, I agree not to question nor seek to influence the religious or political views of others while representing AnMed as a volunteer."
