===Estate of Thornton v. Caldor, Inc.===
{{main|Estate of Thornton v. Caldor, Inc.}}
Caldor was the subject of a lawsuit filed by former employee Donald Thornton, who claimed he was fired by the company for refusing to work on Sunday, which was his [[Sabbath day]]. Thornton contended that by forcing him to work one Sunday a month, Caldor was violating a Connecticut state law that permitted him to observe his Sabbath without opposition from his employer. Caldor contended that the law was unconstitutional as it violated the [[Establishment Clause]] of the [[First Amendment to the United States Constitution]]. The lawsuit was filed in 1980, and eventually the case was heard before the [[United States Supreme Court]], wherein Caldor's position was upheld.
