Good company but I had the worst manager - Inside Sales Agilent Technologies Employee Review

I really thought I would work for Agilent for a long time. My regret is that I joined a team with a horrible manager. This manager played endless mind games with me, promised promotions that were never going to happen, lied about my pay increase and worst of all, she treats people who reported to her differently which contributed to my overall unhappiness and not to mention, a toxic work environment under her. I do not regret leaving the company but I wish the company had done something with her given that team raised multiple complaints. Management acted slowly and dragged their feet.
