"It also includes using mobile phones to send unwanted messages, unwanted sexual advances and ‘unwanted or uninvited physical or verbal contact or engagement’, possibly including wolf whistling."
What is considered "unwanted or uninvited physical or verbal contact or engagement."
To a certain extent, you can operationalize uninvited "physical contact." But how do you operationalize uninvited "verbal contact or engagement?" What's considered "uninvited engagement?" Not being no more than 3 feet from a woman? 4 feet? Furthermore, what is considered uninvited "verbal engagement?" What if a man at work asks a woman co-worker to go out to to lunch (many colleagues eat lunch together). Is this considered "uninvited verbal engagement" because the women didn't ask the man first? Hence, it is "uninvited."
