Gender equality in the workplace still is a tough nut to crack. But what should be the role of government? Should it interfere?

I often get questions about gender equality. I find this difficult to answer as not all women want to make a career and some prefer to stay at home. We should also respect this. On the other hand, I also believe that some organisations do not always give women equal chances. So therefor my question : should governments interfere in this ? Or is it none of their business ?
