Well you have asked a really difficult question. Do you ever watch So You Think You Can Dance USA? The sub-text could just as well be your question. Do women and men perform similarly that we should understand they are looking for the same or equal salary, paid at the same times. I personally would start by paying men and women on different days of the pay term. Eventually salaries will be just right. What might happen initially is that people will start trying to organise their leave around personal need days, and then unpaid leave, and when that has been perfectly understood by all, everyone will want to eat lunch on site, and happy days...who gets paid for the work they do will realise itself in salary correction requests to HR. Does that mean a raise, maybe do not follow my advice.
