Why do some big hotels recruit clerks, secretaries, receptionists, assistants and sparring partners all the year round? Are these positions reasonable?

Because the hotel industry has a relatively large turnover, they have long been recruiting; However, if there are no vacancies, they will only leave your contact number, so that when someone resigns in the future, they can immediately contact the right person to take the highest position! ! ! Don't worry, the positions you mentioned are all formal! ! I don't know where it is except that sparring partner! !
