Most restaurant chefs have to work 12 hours a day ( or more) 6 days a week. Women just dont want to do that, just as they don't line up to get good paying jobs as plumbers, electricians, brick layers, roofers,  or carpenters which may require long and irregular hours, and being obliged to do emergence weekend and holiday work. They complain about the glass ceiling, when in reality they are content to simply not go there.
