Whether they are a mixed bag or not, it is extremely inappropriate, unethical, and should be illegal for an employer to discourage or manipulate employees into not unionizing or joining a union. This is in my opinion the moral equivalent of your employer giving you unsolicited accounting or medical advice (but actually worse than that, since they have bias on the matter as well) and I hope someday the law reflects that.
