Best answer I can give you is to tell your manager that you liked working the overtime (not everyone does) and that if others dislike it you'd be glad to pick up more of it. 

Or tell them you'd be glad to be switched to a longer working day, which wouldn't get you overtime bonuses but would get you more paid hours. Or ask them what they would need to see from you to justify giving you a raise, if money is your concern. Or several/all of these. 

After that, it's Management's choice, on whatever basis they want to make it (modulo discriminating against protected classes if people).
