Well, should you move to a country like Nicaragua that legally bans all abortions?
By living and working and paying taxes in the USA, a country that tolerates a million abortion killings per year, aren’t you facilitating a great amount of immorality?
Despite what I just said, I do not know what the right answer is.
In a way, if you help sell insurance coverage for birth control pills, that is very similar to working in an abortion clinic and helping people schedule their abortions!
Wait! Here’s what I think you should do: Simply don’t talk about birth control coverage, even if the caller asks about. Simply say something like, “Oh, you want coverage for birth control pills? Excuse me, my phone is cutting out. I’ll have to call you back.” Then hang up. Is that wrong? Well, you are preventing sin, so I think it is justifiable. But don’t announce to your supervisor that you won’t talk about the birth control coverage. And don’t tell any co-worker what you are doing. Secrets are NEVER kept at workplaces!
And, start looking for a better job. There are no good jobs at insurance companies! I’ve worked for several. They ALL treat their customers unjustly when it comes time to paying claims!
