Women of all professions have been replying to a Twitter thread with their experiences of pushing to have their expertise accepted.
Historian Louise Raw, who contributes to BBC Radio London, began the thread highlighting the annoyances faced by women like her with PhDs.
Stories have ranged from women fighting for their job title, to plaudits being mistakenly given to men.
Women, from academia and DJing, told the BBC about dealing with such sexism.
One of the many women with doctorates to respond with their experiences was Dr Penny Pullan.
At her first ever conference, Dr Pullan was casually overlooked by people who assumed her husband, a mathematician, would be there to discuss the topic of superconductivity.
Dr Pullan's dissertation was on Flux Pinning in Yttrium Barium Copper Oxide Superconducting Thin Films.
"I was a PhD student at Cambridge in the Cavendish lab at the time," said Dr Pullan.
When people found out she was the physicist, "they sort of muttered, 'Oh!' and then quickly found someone else to talk to".
"This happened multiple times. I ended up chatting to my husband all evening."
Dr Pullan left academia after her PhD and went into industry.
"Things were much more collaborative! Don't get it wrong, I loved Cambridge and my supervisors and colleagues were fantastic.
"It was those who didn't know me at the conference who automatically assumed I was a wife. That was annoying and made it harder."
Dr Pullan is currently a keynote speaker at a conference for project managers and credits her research presentations at Cambridge, in front of two Nobel Prize winners, as preparing her for the job she does now.
"Give me a few hundred project managers like today and I have no nerves at all and just enjoy it!"
I am an orthopaedic surgeon.I once , whilst wearing a white coat, examined a man’s knee, sent him for an x-ray, told him that he needed a knee replacement and put him on the waiting list. As he was leaving the room, he asked if he would be seeing the doctor today/1— Rachel Magee (@magees) May 19, 2019
A couple of years ago, I was staying at a hotel for a conference. The hotel charged me too much for the stay, when I complained at reception, they asked me to fill in form. Which I did. With my academic title. A little while later the manager arrives. "Ah, it's Sandra, isn't it?"— Dr. Sandra Schwab (@ScribblingSandy) May 19, 2019
'This impacts our lives'
Lady Love, founder of Female DJs London, also replied to the thread to highlight that women DJs can face a similar, and similarly aggravating, confusion.
Although it is often the crowd asking if they should be at the turntables, managers too can be surprised. "Some of our DJs have turned up to play and been asked where the DJ is," she said.
In our industry it’s standard to be asked if we’re the DJ accompanied by a rather puzzled look. You might think being in a venue, behind the decks, headphones on, mixing might be enough of a clue but no.— Female DJs London (@FemaleDJsLondon) May 19, 2019
This is oft followed with “Are those your records” every set for 20 years x
Lady Love says things are worse now than 20 years ago, "whilst we are told they are better".
"The 1990s were a much freer time, there was no abuse. If you look at the DJ top 100 in the 1990s there were more women than today. As the DJ industry got bigger it got more white, more hetero, more male.
"You have to fight for your space, but are never accepted.
"I founded Female DJs London a decade back. We united, put on the biggest showcase of female DJs in history. The industry ignored it."
Festivals, too, are giving women worse slots and less pay, she says.
"It's done on profile. All the highest-paid DJs are male. Women get no opportunities, all the guys book each other.
"It really is quite sickening for an industry supposedly about love and equality.
"You look at line-ups. There are no women. This impacts our lives."
