I wonder if this is generationally specific. I'm an American and have zero expectation that anybody at work should acknowledge my birthday.

On the other hand, I can understand feeling slighted if the manager consistently recognizes their employees' birthdays but overlooks mine.

My only experience with acknowledging birthdays at work is that you do it yourself if you want to. Most jobs I've had, birthdays are just not recognized at all, but at one employer the tradition was that you brought in donuts to share on your birthday (if you wanted to--it wasn't required of course).
