In my last role, there was a female recruited to a senior position from another employer. Even before she started, there were rumours being spread about possible indiscretions / inconsistencies in her last job. No evidence, just speculation. YANBU.
Women tend to be held to higher standards at work generally ime - both in terms of behaviour/'niceness' and professional competence. Senior women are often viewed negatively for exhibiting exactly the same attributes that men get praised for.
