&gt; <i>If you don&#x27;t know by 21 ... you&#x27;re never going to learn</i><p>Ah, the good old &quot;people&#x27;s personalities are set in stone by 21&quot; canard. If people were &#x27;never going to learn&#x27;, then first-wave feminism wouldn&#x27;t have attracted anyone over 20, for example.<p>This kind of statement is just an excuse to throw a person under a bus, rather than take the effort to educate them.<p>&gt; <i>Or at least not in any timeframe where it&#x27;s valid for this company.</i><p>And this is also nonsense. A simple talk can be enough. When I was at university, one of the professors kept asking improper questions of the female students, told to me by a female colleague. I went to my professor and asked what could be done, mentioned what my female colleague said (and stressed that she&#x27;d asked not to be named). My professor had a chat with the questionable professor, and the problem disappeared instantly.<p>It&#x27;s called &#x27;feedback&#x27;, and we ask it of our colleagues, our clients, our trainees and trainers. Some people respond really well to feedback. For those that don&#x27;t, well, at least you tried to improve things rather than kick the can down the road to someone else to deal with.
