You aren't forced, there are a lot of other jobs that don't require you to have sex with the boss.
You ok with this? Don't have an abortion or you will be fired. Don't have a kid or you will be fired. It is always a choice right?
Sure, it isn't 'forced' as in, we will tie you up and someone will give you the vaccine, (same as have sex with me or be fired, technically I won't force myself on you) but basically amounts to the same. And taking in account that a) there are vaccine side effects (I had them and know a few others that also did) b) they don't really help with the spread, just reducing the symptoms, it shouldn't be the business deciding on it.
