It literally stated Take Your Daughter To Work Day.

If anyone bothers knowing the definition before saying it was sexist. The dictionary definition of daughter is:

(n.) a girl or woman in relation to her parents.

Lincoln is a son.

(n.) a boy or man in relation to either or both of his parents.

So clearly, Rita had the "Take Your Son To Work Day" in order to balance it out.
