Writing for Forbes.com, Shaun Rein, founder and managing director of the China Market Research Group, says the reason why men don't promote women more frequently is because females in business are not pushy enough.
He also admits: "I will be honest. In my career, I have tended to promote more men than women. I have even generally given men higher salaries. Why? Am I sexist? Do men do a better job? The answer is a resounding no to both.
"Actually, it is mostly women's fault. They simply don't ask for raises or promotions as often as men do."
In interviews with Rein's organisation, hundreds of women said they believed they would get promoted if they worked hard and showed their value to the company, and also said they feared they would be fired if they appeared too pushy.
However, Rein says: "… the reality is that promotions rarely happen just because you're there and you're good. You need to tell people how good you are. This is especially true at more junior levels, where it can be harder to get noticed and there is more competition for plum positions."
Rein advises those looking for promotion to simply ask for it, along with a raise. He says you have to sell the boss the idea of promoting you and there is no risk in asking to move ahead.
Rein explains: "Promotions are tough to ask for, especially when you're concerned about fitting in. But any woman who wants to rise high in the business world should consider being more aggressive in seeking out promotions and increased responsibility. Approach your boss with a plan, make your case and make sure that no one forgets you are a strong business mind."
