Health care is an industry of intensive labor services and in most countries of the world health workers are represented by a wide range of urgent care professional, technical and support staff working in a wide variety of environmental conditions. In addition to professional physicians, laboratory assistants, pharmacists, social workers, this additionally includes administration, the clergy, administrative staff, nutritionists, engineers, electricians, painters, workers who repair and update the building and the equipment inside it. Unlike direct care physicians, welfare workers are usually only exposed to casual contact with patients.

Part of the health care sector (unfortunately often too small, underfunded in most localities) is represented by direct and indirect preventive care services. However, the main focus of health services is diagnosis, treatment and care. The best urgent care in Los Angeles present the patient with various levels of physical and emotional trust which distinguish them from clients in services such as retail, restaurant and hotel services. They are required, and usually provided, special services and attention which are often urgent. This service is often provided at the expense of the personal convenience and safety of health workers.

Given their size and the number of employees, ambulance services and facilities for chronic patients are perhaps the most visible element of the healthcare industry. They are supplemented by outpatient clinics, “surgical centers” (surgical institutions for outpatients), clinical, pathological and pharmaceutical laboratories, radiology and imaging centers (tomography, scanning), ambulance and emergency vehicles, individual and group rooms and help services on housework. They can be located within the hospital or work elsewhere under its auspices or they can be separate and act independently. It should be noted that there are profound differences in the way medical services are provided.

The healthcare system is complemented by an array of educational and research institutions in which students, medical professionals, researchers and support staff come in direct contact with patients and participate in their treatment. It includes higher medical schools, dental, nursing, educational institutions of public health, social welfare and various technical training centers involved in the provision of health care.

The healthcare industry has undergone profound changes over the past few decades. An aging population, especially in the developed countries is increasing the number of nursing homes with medical care, facilities and services that provide home care. Scientific and technological development has led not only to the creation of new types of facilities staffed by a new generation of specially trained personnel, but also highlighted the role of emergency medical hospitals. Now many services requiring inpatient care are provided on an outpatient basis. Finally, financial constraints dictated by the rising cost of various types of medical care are giving a new form to the healthcare industry, at least in developing countries.

Health workers, wherever they work have direct contact with patients and face many unique dangers. They face the risk of acquiring infections from the patients they serve as well as the risk of skeletal muscle injuries when lifting, carrying or containing them. Support staff not directly involved in patient care (e.g. laundry workers, household workers and movers) not only regularly contact chemicals such as cleaning products and disinfectants in industrial concentrations, but also come into contact with the biological hazard of contact with the infected linen and waste. There is also a moral side to health care which, especially in emergency situations requires the healthcare provider to place the convenience and safety of the patient above their own. The depletion of physical and moral strength as a result of treatment failures, death, and dying often takes their toll. All this is complicated by a special work schedule, intentional or unintentional dismissals, the need to cater to some unreasonable requirements of patients and their relatives. And finally, there is a risk of insulting and attacking patients especially when you need to work alone or in insecure places.
