As evidenced by last year’s infamous Google memo, there somehow still exist those who’ll defend sex and gender-based discrimination with claims of supposedly innate differences (like men being more logical, for instance) that make men more suited for a variety of jobs: “it’s simple biology,” they profess. And while that sort of discrimination is blatantly illegal, no facet of biology is perhaps more pernicious in affecting women’s employment and economic status than pregnancy. The mere possibility of pregnancy can be enough to worry potential employers to the point of hiring someone else – and the reality of it can cost working women needed and well-deserved jobs.
