A new study shows that women face age discrimination in the workplace across different age brackets.
Women under 40 often experience "role incredulity," while women over 60 report being ignored altogether.
Middle-aged women also face age-related discrimination, making it challenging for them to progress in their careers.
Gender-equity researchers believe this stems from the threat middle-aged women pose to insecure men in the workforce, leading to attempts to diminish their roles.
