She absolutely has freedom of conscience. Being fired from a job doesn't touch that.
What she apparently does not have, however, is the right to determine what she will and will not do while on the payroll of Target.
You are absolutely right that this is not a religious debate, nor does it really have anything to do with the morning after pill. It is about her employer requiring something of her, and her refusal to comply.
Employment at will is a 2 way street.
When she started working there, the abortion pill wasn't available. Her employer changed the criteria of her employment.
Under that premise, should every doctor be forced to perform abortions because it's legal?
It is about her employer requiring something of her, and her refusal to comply.
This wasn't a question when she was employed. Is it fair to change her job criteria some years later?
