the relationship at any time, often subject to a certain notice period. This is referred to as at-will employment. The contract between the two parties specifies the responsibilities of each when ending the relationship and may include requirements such as notice periods, severance pay, and security measures. A contract forbidding an employee from leaving their employment, under penalty of a surety bond, is referred to as an employment bond. In some professions, notably teaching, civil servants, university professors, and some orchestra jobs, some employees may have tenure, which means that they cannot be dismissed at will. Another type of termination is a layoff. Wage labor Wage labor is the socioeconomic relationship between a worker and an employer, where the worker sells their labor under a formal or informal employment contract. These transactions usually occur in a labor market where wages are market-determined. In exchange for the wages paid, the work product generally becomes the undifferentiated property of the employer, except for special cases such as the vesting of intellectual property patents in the United States where patent rights are usually vested in the original personal inventor. A wage laborer is a person whose primary means of income is from the selling of his or her labor in this way. In modern mixed economies such as that of the OECD countries, it is currently the dominant form of work arrangement. Although most work occurs following this structure, the wage work arrangements of CEOs, professional employees, and professional contract workers are sometimes conflated with class assignments, so that "wage labor" is considered to apply only to unskilled, semi-skilled or manual labor. Wage slavery Wage labor, as institutionalized under today's market economic systems, has been criticized, especially by socialists, using the pejorative term wage slavery. Socialists draw parallels between the trade of labor as a commodity and slavery. Cicero is also known to have suggested such parallels. The American philosopher John Dewey posited that until "industrial feudalism" is replaced by "industrial democracy", politics will be "the shadow cast on society by big business". Thomas Ferguson has postulated in his investment theory of party competition that the undemocratic nature of economic institutions under capitalism causes elections to become occasions when blocs of investors coalesce and compete to control the state plus cities.
