Ms McMahon worked as a typist at law firm Rothwell & Evans, and was dismissed due to a series of absences.
McMahon had sent an email to a senior lawyer describing how menopause-related hot flushes were “unbearable” and made her feel as though she had flu.
In one email, McMahon said she had been late due to changing her clothes after a hot flush episode, adding that “I don’t want to become unreliable and I’m trying to get a solution… I don’t want to let you down or think bad of me.”
