Askilled worker is anyworker who has specialskill, training, orknowledge which they can then apply to theirwork. A skilled worker may have learned theirskills throughwork experience,on-the-job training, anapprenticeship program or formaleducation. These skills often lead to better outcomes economically. The definition of a skilled worker has seen change throughout the 20th century, largely due to the industrial impact of theGreat Depression andWorld War II. Further changes in globalisation have seen this definition shift further in Western countries, with many jobs moving from manufacturing based sectors to more advanced technical and service based roles. Examples of formally educated skilled labor includeengineers,scientists,doctors andteachers, while examples of less formally educated workers include crane operators, CDL truck drivers,machinists, drafters,plumbers,craftsmen,cooks andbookkeepers.

In the northern region of the United States,craft unions may have served as the catalyst to develop a strong solidarity in favor of skilled labor in the period of theGilded Age (1865-1900).[1]
In the early 1880s, the craft unions of skilled workers walked hand in hand with theKnights of Labor but the harmony did not last long and by 1885, the Knights' leadership became hostile totrade unions. The Knights argued that the specialization ofindustrialization had undermined thebargaining power of skilled labor. This was partly true in the 1880s but it had not yet made obsolete the existence ofcraft unionism.[2]
...The impact ofscientific management upon skilled workers should not be overstressed, especially in the period before World War I.[3]
The period between 1901 and 1925 signals the rise and fall of theSocialist Party of America which depended on skilled workers. In 1906, with the publication ofThe Jungle, the most popular voice of socialism in the early 20th century,Upton Sinclair gave them ignorant "...Negroes and the lowest foreigners —Greeks, Roumanians, Sicilians, and Slovaks" hell.[4]
There was a divergence in status within theworking class between skilled and unskilled labor due to the fall in prices of some products and the skilled workers' risingstandard of living after thedepression of 1929. Skilled workers were the heart of thelabor movement before World War I but during the 1920s, they lost much of their enthusiasm and the movement suffered thereby.[5]
In the 20th century, inNazi Germany, the lower class was subdivided into:
After the end ofWorld War II, West Germany surpassed France in the employment of skilled labor needed at a time when industrialization was sweeping Europe at a fast pace. West Germany's preponderance in the training of skilled workers, was the main factor to outweigh the balance between the two countries. In the period between 1950 and 1970, the number of technicians and engineers in West Germany rose from 160,000 to approximately 570,000 by promoting skilled workers through the ranks so that those who were performing skilled labor in 1950 had already become technicians and engineers by 1970.[7]
In the first decade of the 21st century, the average wage of a highly skilled machinist in the United States of America is $3,000 to $4,000 per month. In China, the average wage for a factory worker is $150 a month.[8]
Inmanufacturing in the United States, there has been a change in the concentration of skilled workers from the areas of past economic might e. g. steel, automobile, textile and chemicals to the more recent (21st century) industry developments e. g.computers,telecommunications andinformation technology which is commonly stated to represent a plus rather than a minus for the Americanstandard of living.[9]

In addition to the general use of the term, various agencies or governments, both federal and local, may require skilled workers to meet additional specifications. Such definitions can affect matters such asoccupational licensing and eligibility fortravel orresidency. For example, according toUS Citizenship and Immigration Services, skilled worker positions are not seasonal or temporary and require at least two years of experience or training.[10]
Skilled work varies in type (service versus labor), education requirements (apprenticeship versus graduate college) and availability (freelance versus on-call). Each differences are often reflected intitling, opportunity, responsibility and (most significantly) salary.
Both skilled and non-skilled workers are vital and indispensable for the smooth-running of a free-market and/orcapitalist society. According toAlan Greenspan, former chairman of theFederal Reserve Bank, "Enhancing elementary and secondary school sensitivity to market forces should help restore the balance betweenthe demand for and the supply of skilled workers in the United States."[11]
Generally, however,individual skilled workers are more valued to a given company thanindividual non-skilled workers, as skilled workers tend to be more difficult to replace. As a result, skilled workers tend to demand more in the way of financial compensation because of their efforts. According to Greenspan,corporate managers are willing to bid up pay packages to acquire skilled workers as they identify the lack ofskilled labor as one of today's greatest problems.[12]
Skills can be delivered in a variety of manners, and iscertified,licensed or acknowledged through various means:
Shortages of skilled worker have been attributed on shortcomings of the educational sector[13][14] and lowremuneration.[15]
Skilled workers are valuable assets to companies. Benefits of a skilled workforce include:
Human capital flight is the migration of skilled workers from places of lower to higher opportunities in terms of training, working conditions, materialistic rewards and security.[16][17] Human capital flight is a concern due to the richest nations benefiting from educational investment of the nations who can least afford to lose the most productive career years of their highly skilled professionals. This factor disincentives investment in education in both the developing and developed world, as foreign students and foreign workers limit opportunities for citizens in the receiving countries.[18] Some developing countries see the migration of domestically trained professionals abroad not as a drain but as a gain, a "brain bank" from which to draw at a price; for these professionals, on their return with their accumulated skills, would contribute to the growth of the homeland; cultural factors favor the return of these professionals for a short or a long while.[19] However, policy in the United States is geared toward making non-immigrant visas eligible for adjustment of status to permanent residence status.[20]
The demand forInformation Technology (IT) skilled workers is on the rise. This has led to a lessening of the immigration restrictions prevalent in various countries. Migration of skilled workers from Asia to the United States, Canada, the United Kingdom and Australia is common, specially among students and the temporary migration of IT skilled workers. Data shows, however, that the migration of skilled workers from Canada, Germany, the United Kingdom and France to the United States is only temporary and is more like a brain exchange than a "brain drain".[21]
Brain Drain literature focuses mainly on the high cost of skilled migration for the homeland or sending country. This loss can be partly offset if the migration is only temporary. Developing countries invest heavily in education. However, temporary migration can generate a substantial remittance of capital flow to the homeland. This flow of capital plus the additional knowledge gained would do more than compensate the homeland for the investment made originally in educating the skilled worker. The key to temporary migration is a change in the trade and immigration policies of the receiving country and a stepping-up of the demands of the sending country for the return migration of skilled workers.[22][23]
On January 1, 2015, the Government of Canada implemented the Express Entry Immigration system under the Economic Class including the Federal Skilled Worker Program. Under Express Entry, Federal Skilled Workers across 347 eligible occupations who meet minimum entry criteria, submit an expression of interest profile to the Express Entry Pool. The profiles of candidates in the pool are ranked under a Comprehensive Ranking System.[24]
UnderApartheid, the development of skilled workers was concentrated on the white inhabitants but after the socio-political upheaval of the 1990s, these same skilled workers are emigrating, a highly sensitive subject in contemporary South African Society. The media inSouth Africa has increasingly covered the "brain drain" in the 1990s. Starting in 1994, when a democratically elected government took control of the reins of power, official South African statistics show a greater emigration of skilled workers. The validity of this data has been questioned.[25][26]
The European Union brought policy into force that paved the way for skilled workers from outside the Union to work and live in the EU under theBlue Card (European Union) Scheme. The key reasons for introducing this policy are an ageing population in general and an increasing shortage of skilled workers in many member states.
But flying under the radar are several administrative changes aimed at highly skilled immigrant workers and entrepreneurs, including increased job portability for immigrants with approved employment-based petitions but who can't get a visa because of annual caps, expansion of the optional practical training program, a review of the permanent labor certification program, and guidance on L-1B intracompany transferee visas for "specialized knowledge" workers.
