Depended on the institution, but in general males were predominant in management and programmer positions. Operators were split about 50/50 at the places I worked, and I never met a male keypuncher. I/O control staff (who gathered input data, scheduled batch jobs to run, and distributed printed output) were mostly women. If you were male, you wore a tie. Those of us kids who didn't know how to tie one (or who operated drum printers and high-speed decollators) were forgiven for wearing clip-ons. I worked one place where men were required to wear ties, and the women all wore a uniform dress.
