Final answer:
The high turnover rates in the U.S. hospitality industry are primarily due to seasonal employment, where workers are often hired temporarily during peak seasons, affecting job stability and satisfaction.
Step-by-step explanation:
The major reason for the high turnover rates in the U.S. hospitality industry is d) Seasonal employment. This sector is characterized by fluctuating demands throughout the year, leading to periods where temporary or seasonal staff are hired in large numbers. With the nature of the job market in this industry, employees often find themselves looking for new opportunities once the peak season is over, contributing to the high turnover rates. Furthermore, overall job satisfaction can be impacted by several factors, including the level of autonomy and the content of the work, which might not always be optimal in hospitality roles that are seasonal or lower in pay and benefits.
