ummmm, yes it is. a woman can NOT be denied a job or an advancement based on her being pregnant or based on the possibility of her being pregnant.
Pregnancy Discrimination Act of 1978
This law was drawn up to close the above-mentioned loophole. This legislation stipulated that all employers treat pregnant and non-pregnant employees in the same way, both in terms of benefits received and all other respects.
Family and Medical Leave Act of 1993
When it passed in 1993, the Family and Medical Leave Act (FMLA) was hailed as a ground-breaking law that provided important federal protections for both men and women faced with issues related to pregnancy, childbirth, adoption, placement for foster care, and family sickness. It was bitterly opposed by some segments of the business community, but family advocates ultimately prevailed. The FMLA stipulates that men and women may take as many as 12 weeks of unpaid leave annually for the birth or adoption of a child, care of a sick child, placement for foster care, or because of morning sickness or other illness (the illness does not have to be pregnancy-related). Employers and employees alike should note, however, that the FMLA does not impact businesses with fewer than 50 employees.
