Democrats in the Missouri Senate say a proposed change in workplace discrimination law would set civil rights back by 40 years. Senator Victor Callahan of Independence says the change would affect age as well as race.

Senator Brad Lager of Savannah says he introduced the bill because the courts have made it too easy to sue businesses. The bill would require proof that discrimination was a “motivating factor,” not just a “contributing factor,” in an employer’s action. Debate could resume this week.
