The cause is perhaps not difficult to understand. When the company is in need of professional services, they may take the painful step of spending an amount of money to send an employee to be trained. But the boss wife, always on duty and entangled with little details, has few chances indeed for advanced study.
原因或許不難理解，公司有業務需要時，可能會忍痛拿一筆錢讓員工去上課、受訓，而永遠瑣事纏身，必須「坐鎮」的老闆娘，卻少有進修的機會。
