This chapter discusses the impact of motherhood in the form of maternal wall bias, which analysis suggests is the strongest form of gender bias. This bias is particularly damaging because mothers often face a wage penalty due to the stereotype that they will be less competent and prioritize their family over their career, while fathers may experience a wage premium, being stereotyped as harder workers who provide for their family. This means that efforts to decrease the wage penalty for mothers must also address the wage premium for fathers. The chapter explores multiple biases faced by mothers in the workplace. They navigate a "tightrope" between appearing too committed to their work, thus seen as neglecting their family, and being too attentive to their family, thus considered unreliable workers. Upon returning from maternity leave, mothers often have to "prove it again" to their colleagues. Frequently, women are criticized for pursuing opportunities or promotions when they are mothers, often due to comments about it being overwhelming or selfish to prioritize their careers. The chapter also addresses flexibility stigma-the notion that women who work part-time to raise children face fewer opportunities, and men who take parental leave are seen as "less masculine" by their coworkers. Ultimately, the stigma revolves around perceived femininity and its negative connotations. The chapter concludes with bias interrupters to address this complex issue, including ensuring that both men and women take the full amount of leave allotted to them and creating a seamless transition process in the workplace to facilitate this.
