The quotation marks enclose too much. Also, that should be bring, not take (since, y’know, the parent will be there anyway).
It’s “Bring Your Child to Work” Day, and the father works at Area 51.
The capitalization for the name of the day isn’t required, but the names of such events are capitalized more often than not.
I don’t know why anyone would hyphenate Area 51… *shakes head*
