This is a question from Managerial Implications from Chapter 13 of the book international business law and its environment by Schaffer, Agusti, and dhooge.
"Your company has an office in Spain. You have hired a worker, Ms. Jimenez, for a float term and have renewed her contract twice. Shortly after renewing it for the second time, you discover she will be giving birth within three months. You send her a note stating that she is terminated effective in one month (which is two months before her due date). You believe that since she was only on a limited-term contract, she cannot expect to be treated like a more permanent employee and given all maternity benefits. Are there any legal concerns here? What impact might this decision have on the advancement of women in employment? How will this affect your hiring practices?"
