> Despite having over 10 years of experience, some of my colleagues feel the need to explain basic concepts that I already know. I'm assigned the easiest tasks. No one comes to me for help, although I'm the most knowledgable. No one takes my opinions into consideration. I'm a white straight guy with 18 years of experience (although Slavic), but exactly the same things happen all the time in office. Not saying his story might be different, but often people attribute struggles to race/gender/nationality, while it's actually just competition or just how things are.
