I have just read the original article, and to be honest, I have seen what it is describing first hand. At 35, I am lucky enough to be a Reader in a hard-science at a Russell Group university and I am a man. Most of my peers who are women - the people I did a PhD with - either dropped out of academia, or are still postdocs (10 years!). If they happen to be lucky enough to have an academic job, they are part-time (looking after children) suffering discrimination by a largely male management, often with such a huge teaching and administration load, they wonder why they ever wanted to be an academic.
Some examples:
One of my peers (at another institute) has no fewer than 100 students she must give tutorials to each week, plus three lecture courses per semester. She works a 90+ hour week, does next to no research, and watches her colleagues around her get promoted because they have been successful in gaining funding.
Another peer (at a different institute) was given three lecture courses and a large departmental administrative load, 1 month after returning from maternity leave. Within a year, she was given another 3 lecture courses, making 6 plus the admin job. She only worked part-time. Her full-time (male) colleagues only had 4 lecture courses, or 2 plus an admin job. She actually told me she got pregnant the second time as she wanted out of her job.
I look at this situation and at every opportunity I try to correct it. But I can't, single handed, change an entire sector. What can be done?
