Well think of it this way. If you joined the army and instead of doing what the job description implied you were forced to retrieve coffee for your boss, adjust things in his room because he's too lazy to do it himself, forced to endure constant sexual harassment to the point where your boss is physically touching you and groping you, occasionally even raping you. in addition to all of this you are paid less than people who do less work than you, even if you work for years you will not receive a promotion while others will receive promotions for doing much much less work, you're paid significantly less, and if you ever speak up or talk about this you will be at risk of being fired.
