Pretty easy to train a high school graduate, or a PhD, to become a waiter in a few days if not hours. Someone finishing a high end watch? A bit harder i think=) So if you fire these people and they arent working, when demand does come back (and these are cyclical businesses, demand will return), and you dont have enough qualified trained watchmakers, you have a big problem as a business. A restaurant can cater to demand week by week with part time labor --- most industries, such as watches, have to balance near term demand with having a labor force for the long term normalized demand. These are cyclical businesses --- they always look like they have too many people in downturns, and too few people in upturns
