14. Skyscraper Window Glass Cleaners
For one to become a professional skyscraper window glass cleaner, he/she must be very courageous and possess tremendous cleaning and balancing skills. There’s no place for individuals suffering from fear of heights, because as the name suggests; you’ll be working hundreds of meters above the ground with little suspension and safety harness as your only savior.
In certain situations, you’ll only have a narrow sill to balance on and still ensure that the windows are impeccably cleaned without cracking or breaking them. Any slight mistake and you’ll plunge to your death. This is certainly not for the faint hearted.
