We recently offered a full time role to an applicant who has now indicated that she may be pregnant.  She is considering not joining us because of this.

We have no problem with her pregnancy but the role offered could be strenuous in later months of pregnancy.  We want to consider other options rather than lose a good applicant. 

One option is to offer a 6 month fixed term contract in this or an alternative role.  Would we be discriminating against her because of her pregnancy if we offered different terms now?  

Also, would she have the right to return to work?
