Equal pay for equal work

I think that it isn't important if the worker is a man or a woman, the important for me is the work.
I don't know why the woman salary is inferior & a man salary if they do the same work.
more people think that the women work is bad and I can't understand it. women can do the same work of men and & do it well.
I think that every person who works in & equal work nedd to have & equal salary.
In conclusion, the important is if the worker do well her / his work, not if it is a women or men.
