Ruas61, I am so sorry. That was very, very wrong of whomever did it. That violates the principles of hospice, and you should complain to the agency you used. If they have a need for retraining, or to fire someone because they cannot do their job with the proper respect for their patients' spiritual wishes and directives, then they need to know that.
The only time I've brought my "religious agenda" into healthcare is in discussions here, and in asserting that I would not be able to participate in certain acts. Certainly, just as patients have a right to opt out, so should health care workers. I can't stop someone else from doing anything, but I have lines I cannot cross.
My hospice gives us great training on respecting religious boundaries and giving the patient the support they need and request, and not making assumptions based on what they nominally call themselves. I'm sorry it seems all hospices don't do the same.
