Rate of unemployment of women engineers

I wanted to start write writing about the employment for women engineers, because, women engineers are rejected in this field. Because all the time the engineering has traditionally been a field of for men, and when woman could go into in this field, it seem as like men feel attacked threatened by them, and they don't allow the women's entry.

In almost all Almost everywhere in the world, women have less a lower salary and fewer professional rise opportunities in the engineering, especially, when the job implicate requires on-site work, for example "Building work, electrical on-site work" like working at a construction site or doing on-site electrical work.

When a woman arrives to start work in this these places, she has must bear to endure things, such as: insults, sicko [not sure of the intent here. "Sicko" is too informal. Maybe "lascivious"?]  looks, sexist language, rejection and violations of labour rights.
I think that, it is not possible, that in the century XXI, women even must live this things. How can it be that in the twenty first century, women still have to put up with these things?
When will the world be different for us? This is the big question, that all women and men must do all the days continue to ask, and try give it solution, to resolve with their acts and changes.
