It kinda seems like you’ve never seen the show. I’m well aware of what a Yeoman does on a ship and it is not limited to bringing the captain tea and having the log dictated to you (or you just stand there while dude writes it). Those are, however, things that a secretary did in the 60s. I’m not reducing their roles, there’s a reason that women were only given positions on the bridge that were traditionally filled by women in 60s offices and that the female first officer was removed from the show.
