I feel sorry for her, and her story is probably an example of sexism at the workplace. That is when her boss says that Martin's style is feminine and that that is bad.

However, the linked Martin's story is not a good test of sexism, because the one customer example is anecdotal and sometimes if you pretend to swap customer reps, you end up with a better experience because the customer feels like they are "starting over".

The week-long experiment is also a bad example because it is not a double blind test. Martin could have acted differently than he normally does knowing that he signs as a female.

And even if they did do a double-blind test, another reason for more rude replies directed at female employees could be that social expectations are different. That is the same word choice by people of different genders/sexes can imply different things. This is not necessarily "bad".
