In country D laws and case law explicitely allow a pregnant woman to withhold any information regarding her pregnancy to employer or potential employer. Especially, she may without any negative consequence lie in interviews, if asked whether she is pregant.
The intention is, that the state intents to ensure that no woman is denied a job due to being pregnant based on the braoder intent to avoid economic hardship for expetant mothers.
The only legal consequence of lying to employer or potential employer is that the employer is not responsible for any damage caused due to lack of knowlegde by being unable to adjust the woman’s work situation and requirements accordingly (e.g. if a woman is pregnant and works with embryotoxic material, the employer is not responsible for any damage to the child as long as employer is not told about pregnancy).
A applies for the job and expects she would not get the job, if the employer would know she is pregnant, because the employer has a strong bias against female employes with young children being lazy; but A thinks she will nontheless do the job well (having a husband and family helping her with caring for the child; presume that its not harmful for the child if she has a job); she also needs the job to avoid her family relying on welfare; she gets asked by employer B, whether she is pregnant or plans to become pregnant soon; A lies and gets the job.
Did A sin?
If A asked beforehand about whether she should lie and C encouraged her to lie, if asked, did C sin?
