1. Acknowledge (to your team) that these challenges occur & are NOT ok.
It should be very clear to your entire team (regardless of their gender) what behavior is not acceptable from guests.
And make sure to familiarize yourself with local Harassment laws and policies*.
I personally find the #ThatsHarassment videos useful.
It might seem obvious, but your team needs to hear from you pubically what is considered ‘not ok’ to feel empowered.
*What is defined as “Harassment” or “Sexual Harassment” varies greatly from country to country so you’ll need to come up with your own company taking into account both local laws, the cultures of your guests, and also what your guides are comfortable with.
