Whose religious freedom?

An important question for Congress

Jehovah's Witnesses do not believe in blood transfusions.
If my boss is a Jehovah's Witness, can he prevent my health insurance from covering blodd transfusions?

Some Christian Scientists do not even believe in doctors.
If my boss is one, can he prevent my health insurance from covering doctor's visits, insulin, antibiotics, or vaccines?
If he believes in prayer, not medicine, can he require me to "pray" my medical problems away?

Does "Religious Freedom" really mean that my boss has the freedom to impose his religious beliefs on me?
