Do women need to act macho in the workplace?

Do women need to act like men in order to succeed at work?
Apparently many feel they do, with UK research showing that women are deliberately changing their behaviour at work to assume ‘male’ characteristics to be successful. According to a 2013 survey carried out by O2, women are consciously hiding emotions, dressing in a more masculine way, exaggerating assertiveness, and even mirroring the behaviour of male colleagues.
