I've been accused of groping a woman at staff party when I hadnt. Other colleagues knew my married male manager was having an affair with this single mum and was at it in a room with all the coats. I was asked to go get a coat by a colleague that knew what was going on and I walked in on them so walked straight back out.
Monday morning to save face, she accused me of groping her and spread it around the company. I left shortly after that incident, it became untenable to stay on.
Women have reputations to uphold, so will often lie to maintain them, laws are in their favour.
