Let's split it up first! A "sector" is a distinct area, division, or branch of activity. Here, "hospitality" is the business of housing or entertaining guests. So, the "hospitality sector" is the specific area or industry where hospitality is put into practice as a business. Such as a hotel, reception, restaurants, cafes, and so on. Ex: The education sector has grown outside of the traditional classroom space. Ex: I've worked in the hospitality sector for fifteen years now. I love working with people.
