The tertiary sector of the economy (also known as the service sector or the service industry) is one of the three economic sectors, the others being the secondary sector (approximately the same as manufacturing) and the primary sector (agriculture, fishing, and extraction such as mining).
The service sector consists of the "soft" parts of the economy, i.e. activities where people offer their knowledge and time to improve productivity, performance, potential, and sustainability, what is termed affective labor. The basic characteristic of this sector is the production of services instead of end products. Services (also known as "intangible goods") include attention, advice, access, experience, and discussion. The production of information is generally also regarded as a service, but some economists now attribute it to a fourth sector, the quaternary sector.
Personal life is the course of an individual's life, especially when viewed as the sum of personal choices contributing to one's personal identity. It is a common notion in modern existence—although more so in more prosperous parts of the world such as Western Europe and North America.]citation needed[ In these areas, there are service industries which are designed to help people improve their personal lives via counselling or life coaching.
In the past, before modern technology largely alleviated the problem of economic scarcity in industrialised countries, most people spent a large portion of their time attempting to provide their basic survival needs, including water, food, and protection from the weather. Survival skills were necessary for the sake of both self and community; food needed to be harvested and shelters needed to be maintained. There was little privacy in a community, and people were identified by their social role. Jobs were assigned out of necessity rather than personal choice.
Aircraft ground handling
Bag tags, also known as baggage tags, baggage checks or luggage tickets, have traditionally been used by bus, train and airline companies to route passenger luggage that is checked on to the final destination. The passenger stub is typically handed to the passenger or attached to the ticket envelope: a) to aid the passenger in identifying their bag among similar bags at the destination baggage carousel; b) as proof—still requested at a few airports—that the passenger is not removing someone else's bag from the baggage reclaim hall; c) as a means for the passenger and carrier to identify and trace a specific bag that has gone astray and was not delivered at the destination.
The carriers' liability is restricted to published tariffs and international agreements.
In aviation, aircraft ground handling defines the servicing of an aircraft while it is on the ground and (usually) parked at a terminal gate of an airport.
Many airlines subcontract ground handling to airports, handling agents or even to another airline. According to the International Air Transport Association (IATA), conservative estimates indicate airlines outsource more than 50 per cent of the ground handling that takes place at the world's airports. Ground handling addresses the many service requirements of an airliner between the time it arrives at a terminal gate and the time it departs on its next flight. Speed, efficiency, and accuracy are important in ground handling services in order to minimize the turnaround time (the time during which the aircraft must remain parked at the gate).
