The only chance she has now is to fight, to embrace the fight. From that email, I'd give that about a 5% chance. She'd have to set the alpha up and rip her down leading to an insecure "pack". At that point, the pack would divide loyalties up (social to one, political capital to the other) and she could exploit that, either nullifiying the methods the alpha would use or removing her directly.
Otherwise, they will slowly sabotage her while increasing her social stress level. 6 months would be my projection, without considering factors like length of service, age, alternative employment.
