International Labour Organization in the context of "Freedom of association"

The constitution of the United Kingdom comprises the written and unwritten arrangements that establish the United Kingdom of Great Britain and Northern Ireland as a political body. Unlike in most countries, no official attempt has been made to codify such arrangements into a single document, thus it is known as an uncodified constitution. This enables the constitution to be easily changed as no provisions are formally entrenched.

The Supreme Court of the United Kingdom and its predecessor, the Appellate Committee of the House of Lords, have recognised and affirmed constitutional principles such as parliamentary sovereignty, the rule of law, democracy, and upholding international law. It also recognises that some Acts of Parliament have special constitutional status. These include the Magna Carta, which in 1215 required the King to call a "common counsel" (now called Parliament) to represent the people, to hold courts in a fixed place, to guarantee fair trials, to guarantee free movement of people, to free the church from the state, and to guarantee rights of "common" people to use the land. After the Glorious Revolution, the Bill of Rights 1689 and the Claim of Right Act 1689 cemented Parliament's position as the supreme law-making body, and said that the "election of members of Parliament ought to be free". The Treaty of Union in 1706 and the Acts of Union 1707 united the Kingdoms of England, Wales and Scotland, the Acts of Union 1800 joined Ireland, but the Irish Free State separated after the Anglo-Irish Treaty in 1922, leaving Northern Ireland within the UK. After struggles for universal suffrage, the UK guaranteed every adult citizen over 21 years the equal right to vote in the Representation of the People (Equal Franchise) Act 1928. After World War II, the UK became a founding member of the Council of Europe to uphold human rights, and the United Nations to guarantee international peace and security. The UK was a member of the European Union, joining its predecessor in 1973, but left in 2020. The UK is also a founding member of the International Labour Organization and the World Trade Organization to participate in regulating the global economy.

Welfare spending is a type of government support intended to ensure that members of a society can meet basic human needs such as food and shelter. Social security may either be synonymous with welfare, or refer specifically to social insurance programs which provide support only to those who have previously contributed (e.g. pensions), as opposed to social assistance programs which provide support on the basis of need alone (e.g. most disability benefits). The International Labour Organization defines social security as covering support for those in old age, support for the maintenance of children, medical treatment, parental and sick leave, unemployment and disability benefits, and support for sufferers of occupational injury.

More broadly, welfare may also encompass efforts to provide a basic level of well-being through subsidized social services such as healthcare, education, infrastructure, vocational training, and public housing. In a welfare state, the state assumes responsibility for the health, education, infrastructure and welfare of society, providing a range of social services such as those described.

Employment rate, also called the employment-to-population ratio, is a statistical ratio that measures the proportion of a country's working age population (statistics are often given for ages 15 to 64) that is employed. This includes people that have stopped looking for work. The International Labour Organization states that a person is considered employed if they have worked at least 1 hour in "gainful" employment in the most recent week.

The employment-to-population ratio is usually calculated and reported periodically for the economy by the national agency of statistics.

A part-time job is a form of employment that carries fewer hours per week than a full-time job. Workers are commonly considered to be part-time if they work fewer than 30 hours per week. Their hours of work may be organised in shifts. The shifts are often rotational.

According to the International Labour Organization, the number of part-time workers has increased from one-quarter to a half in the past 20 years in most developed countries, excluding the United States. There are many reasons for working part-time, including the desire for a less stressful schedule, having one's hours cut back by an employer and being unable to find a full-time job. The International Labour Organisation Convention 175 requires that part-time workers be treated no less favourably than full-time workers.

Occupational safety and health (OSH) or occupational health and safety (OHS) is a multidisciplinary field concerned with the safety, health, and welfare of people at work (i.e., while performing duties required by one's occupation). OSH is related to the fields of occupational medicine and occupational hygiene and aligns with workplace health promotion initiatives. OSH also protects all the general public who may be affected by the occupational environment.

According to the official estimates of the United Nations, the WHO/ILO Joint Estimate of the Work-related Burden of Disease and Injury, almost 2 million people die each year due to exposure to occupational risk factors. Globally, more than 2.78 million people die annually as a result of workplace-related accidents or diseases, corresponding to one death every fifteen seconds. There are an additional 374 million non-fatal work-related injuries annually. It is estimated that the economic burden of occupational-related injury and death is nearly four per cent of the global gross domestic product each year. The human cost of this adversity is enormous.

The Declaration on Fundamental Principles and Rights at Work was adopted in 1998, at the 86th International Labour Conference and amended at the 110th Session (2022). It is a statement made by the International Labour Organization "that all Members, even if they have not ratified the Conventions in question, have an obligation arising from the very fact of membership in the Organization to respect, to promote and to realize, in good faith and in accordance with the Constitution, the principles concerning the fundamental rights which are the subject of those Conventions".

Debt bondage, also known as debt slavery, bonded labour, or peonage, is the pledge of a person's services as security for the repayment for a debt or other obligation. Where the terms of the repayment are not clearly or reasonably stated, or where the debt is excessively large, the person who holds the debt has thus some control over the laborer, whose freedom depends on the undefined or excessive debt repayment. The services required to repay the debt may be undefined, and the services' duration may be undefined, thus allowing the person supposedly owed the debt to demand services indefinitely. Debt bondage can be passed on from generation to generation.

In 2021, the International Labour Organization estimated that, of the 27.6 million people currently participating in forced labour, 20.9%, or about 5.8 million, were in debt bondage. Debt bondage has been described by the United Nations as a form of "modern day slavery", and the Supplementary Convention on the Abolition of Slavery seeks to abolish the practice.

A labor camp (or labour camp, see spelling differences) or work camp is a detention facility where inmates are forced to engage in penal labor as a form of punishment. Labor camps have many common aspects with slavery and with prisons (especially prison farms). Conditions at labor camps vary widely depending on the operators. Convention no. 105 of the United Nations International Labour Organization (ILO), adopted internationally on 27 June 1957, intended to abolish camps of forced labor.

In the 20th century, a new category of labor camps developed for the imprisonment of millions of people who were not criminals per se, but political opponents (real or imagined) and various so-called undesirables under communist and fascist regimes.
