It seems utterly and incredibly sexist today, but 60 years ago many companies required female employees to resign when they married. This internal memo marks the day that IBM decided that was a stupid idea.
Dated January 10, 1951, the message describes a "temporary modification" on IBM's personnel policy -- one that finally allowed its female employees to continue working once they were married. From the memo:
Effective immediately and until further notice:
1. A female employee will not be required to resign from the company upon marriage
2. The Company will consider for employment a married female.
