In my personal experience, I've dealt with some bias and discrimination in the tech field, but it is improving rapidly. To give you an example, I once provided information about why tracking internal tool usage in a specific way would not work, but my manager immediately asked another (male) employee, with no more experience in this arena than I had, whether or not this was true. I have not observed this confirmation behavior when a man answers the question. I also discovered 2 years in to a career that I was being paid a full $20k less than my male colleagues.
Here's the cool part though - this is definitely changing! And quickly! Adobe has implemented in-depth, anti-bias training for all managers, and it's made a big difference. I rarely experience this sort of "checking with the guys" behavior anymore, and never from people who have worked with me and know my skills. Also, Adobe has achieved pay parity in the U.S. and is well on its way to doing the same in India. https://www.businesswire.com/news/home/20171207005348/en/Media-Alert-Adobe-Achieves-Pay-Parity-U.S.
Actually, no! thankfully, that doesn't really happen in the science field. It happens more in the management field. I just came across this wonderful site about women in STEM. its such a treasure of helpful links and advice!
