Gender Pay Gap - Senior Analyst CBRE Employee Review

i am appalled to recently have discovered a fellow colleague of mine made $5,000 more in his base salary than me despite having no actual commercial real estate experience (me having FIVE years when i started at CBRE) and less education than me. he was offered a range, whereas i was simply offered a number. why? because he’s married? because he’s a man? this is deeply upsetting. this company talks a big talk about diversity and gender equality and yet here we are.
