I worked for a large government department once. We had targets of not only the amount of women we had to recruit but also minority groups such as people with disabilities and certain ethnic backgrounds. We had a percentage target of our workforce that had to be made up of X amount of whoever by a certain date.
What happened is obvious. We had to take people that clearly weren't suitable for the role but made us look good on paper. We had to meet our "targets". What ended up happening is the same amount of work had to be done by fewer and fewer capable people who in turn left the department because of dramatically increased work load. When a senior manager blew the lid on the whole thing he was branded "sexist and racist".
All he did was tell the truth.
