This seems to be more of a normal thing these days, right?

My wife is expecting our first child. Yesterday, I asked my boss for paternity leave. I think I'm allowed 12 weeks by law, but I'm not sure. She practically laughed in my face and told me to man up. She says as a factory worker, it's a bad look if I take a leave because the other men will make fun of me. She also said my wife deserves the leave, not me because she is doing all of the work by giving birth. I think men deserve as much leave as women so they can bond with their child. My boss disagrees. What do you think? Is she right?
