Essentialia negotii (English: essential aspects or basic terms) is a Latin legal term used in contract law. It denotes the minimum contents of a contract in order for it to be held effective and legally binding.
However, the court may not just hold that a contract is invalid. In England, the Sale of Goods Act 1979 s.8(2) states ‘the buyer must pay reasonable price’ when a contract of sale is silent on price. Accordingly the absence of price may not be fatal to a contract of sale.
Accidentalia negotii are additional agreements that can be regulated in a contract. They are ancillary points, opposed to essentialia negotii.
In contracts of employment, essential terms can include not just pay and a basic job description (the work-wage bargain) but also to specifics on holidays, a notice period in the event of dismissal, the place of work, any collective agreements and whether the job is expected to be permanent or a fixed term contract. These are examples under European Union law, implemented under Directive 91/533 on an employer's obligation to inform employees of the conditions applicable to the contract of employment relationship . [1] Article 2 of the Directive states,
"1. An employer shall be obliged to notify an employee to whom this Directive applies hereinafter referred to as the "employee", of the essential aspects of the contract or employment relationship"
All countries in the European Union are required to "translate" directives into national legislation. An example of this is the Employment Rights Act 1996, section 1, in the United Kingdom, which sets out the obligation of employers to supply employees with a statement of written particulars within two months of employment beginning.
In the English speaking world, this notion has not survived as well as in civil law jurisdictions, for the doctrine of consideration has essentially covered the requirement of essential terms in basic bargains. However the concept of what is "essential" changes according to the nature of a particular contract, and so there may be fewer "essentials" in the case of a simple shopping exchange, and more essentials necessary for the proper functioning of a contract in the case of renting a home, taking out a bank loan or pursuing a career.
Labour laws, labour code or employment laws are those that mediate the relationship between workers, employing entities, trade unions, and the government. Collective labour law relates to the tripartite relationship between employee, employer, and union.
Collective bargaining is a process of negotiation between employers and a group of employees aimed at agreements to regulate working salaries, working conditions, benefits, and other aspects of workers' compensation and rights for workers. The interests of the employees are commonly presented by representatives of a trade union to which the employees belong. A collective agreement reached by these negotiations functions as a labour contract between an employer and one or more unions, and typically establishes terms regarding wage scales, working hours, training, health and safety, overtime, grievance mechanisms, and rights to participate in workplace or company affairs. Such agreements can also include 'productivity bargaining' in which workers agree to changes to working practices in return for higher pay or greater job security.
United Kingdom labour law regulates the relations between workers, employers and trade unions. People at work in the UK have a minimum set of employment rights, from Acts of Parliament, Regulations, common law and equity. This includes the right to a minimum wage of £11.44 for over-23-year-olds from April 2023 under the National Minimum Wage Act 1998. The Working Time Regulations 1998 give the right to 28 days paid holidays, breaks from work, and attempt to limit long working hours. The Employment Rights Act 1996 gives the right to leave for child care, and the right to request flexible working patterns. The Pensions Act 2008 gives the right to be automatically enrolled in a basic occupational pension, whose funds must be protected according to the Pensions Act 1995. Workers must be able to vote for trustees of their occupational pensions under the Pensions Act 2004. In some enterprises, such as universities or NHS foundation trusts, staff can vote for the directors of the organisation. In enterprises with over 50 staff, workers must be negotiated with, with a view to agreement on any contract or workplace organisation changes, major economic developments or difficulties. The UK Corporate Governance Code recommends worker involvement in voting for a listed company's board of directors but does not yet follow international standards in protecting the right to vote in law. Collective bargaining, between democratically organised trade unions and the enterprise's management, has been seen as a "single channel" for individual workers to counteract the employer's abuse of power when it dismisses staff or fix the terms of work. Collective agreements are ultimately backed up by a trade union's right to strike: a fundamental requirement of democratic society in international law. Under the Trade Union and Labour Relations (Consolidation) Act 1992 strike action is protected when it is "in contemplation or furtherance of a trade dispute".
In employment law, constructive dismissal occurs when an employee resigns due to the employer creating a hostile work environment. This often serves as a tactic for employers to avoid payment of statutory severance pay and benefits. In essence, although the employee resigns, the resignation is not truly voluntary but rather a response to intolerable working conditions imposed by the employer. These conditions can include unreasonable work demands, harassment, or significant changes to the employment terms without the employee’s consent.
An employment contract or contract of employment is a kind of contract used in labour law to attribute rights and responsibilities between parties to a bargain. The contract is between an "employee" and an "employer". It has arisen out of the old master-servant law, used before the 20th century. Employment contracts relies on the concept of authority, in which the employee agrees to accept the authority of the employer and in exchange, the employer agrees to pay the employee a stated wage.
Australian labour law sets the rights of working people, the role of trade unions, and democracy at work, and the duties of employers, across the Commonwealth and in states. Under the Fair Work Act 2009, the Fair Work Commission creates a national minimum wage and oversees National Employment Standards for fair hours, holidays, parental leave and job security. The FWC also creates modern awards that apply to most sectors of work, numbering 150 in 2024, with minimum pay scales, and better rights for overtime, holidays, paid leave, and superannuation for a pension in retirement. Beyond this floor of rights, trade unions and employers often create enterprise bargaining agreements for better wages and conditions in their workplaces. In 2024, collective agreements covered 15% of employees, while 22% of employees were classified as "casual", meaning that they lose many protections other workers have. Australia's laws on the right to take collective action are among the most restrictive in the developed world, and Australia does not have a general law protecting workers' rights to vote and elect worker directors on corporation boards as do most other wealthy OECD countries.
The Transfer of Undertakings Regulations 2006 known colloquially as TUPE and pronounced TU-pee, are the United Kingdom's implementation of the European Union Transfer of Undertakings Directive. It is an important part of UK labour law, protecting employees whose business is being transferred to another business. The 2006 regulations replace the old 1981 regulations which implemented the original Directive. The law has been amended in 2014 and 2018, and various provisions within the 2006 Regulations have altered.
Labor relations or labor studies is a field of study that can have different meanings depending on the context in which it is used. In an international context, it is a subfield of labor history that studies the human relations with regard to work in its broadest sense and how this connects to questions of social inequality. It explicitly encompasses unregulated, historical, and non-Western forms of labor. Here, labor relations define "for or with whom one works and under what rules. These rules determine the type of work, type and amount of remuneration, working hours, degrees of physical and psychological strain, as well as the degree of freedom and autonomy associated with the work." More specifically in a North American and strictly modern context, labor relations is the study and practice of managing unionized employment situations. In academia, labor relations is frequently a sub-area within industrial relations, though scholars from many disciplines including economics, sociology, history, law, and political science also study labor unions and labor movements. In practice, labor relations is frequently a subarea within human resource management. Courses in labor relations typically cover labor history, labor law, union organizing, bargaining, contract administration, and important contemporary topics.
The New Zealand Employment Relations Act 2000 is a statute of the Parliament of New Zealand. It was substantially amended by the Employment Relations Amendment Act 2001 and by the ERAA 2004.
In Australia, labour hire is referred to by the legal term of art labour hire arrangement, and it refers to the employment practice of an employer supplying its employees to another workplace, for profit.
Consideration is a concept of English common law and is a necessity for simple contracts but not for special contracts. The concept has been adopted by other common law jurisdictions.
English contract law is the body of law that regulates legally binding agreements in England and Wales. With its roots in the lex mercatoria and the activism of the judiciary during the Industrial Revolution, it shares a heritage with countries across the Commonwealth, from membership in the European Union, continuing membership in Unidroit, and to a lesser extent the United States. Any agreement that is enforceable in court is a contract. A contract is a voluntary obligation, contrasting to the duty to not violate others rights in tort or unjust enrichment. English law places a high value on ensuring people have truly consented to the deals that bind them in court, so long as they comply with statutory and human rights.
Agency worker law refers to a body of law which regulates the conduct of employment agencies and the labour law rights of people who get jobs through them. The typical situation involves the person going to an employment agency and then the employment agency sending the person to an actual employer for proper work.
European labour law regulates basic transnational standards of employment and partnership at work in the European Union and countries adhering to the European Convention on Human Rights. In setting regulatory floors to competition for job-creating investment within the Union, and in promoting a degree of employee consultation in the workplace, European labour law is viewed as a pillar of the "European social model". Despite wide variation in employment protection and related welfare provision between member states, a contrast is typically drawn with conditions in the United States.
Alemo-Herron v Parkwood Leisure Ltd (2013) C-426/11 is an EU law and UK labour law case concerning whether an employer may agree to incorporate a collective agreement into an individual contract, and if that agreement has a provision for automatic updating of some terms, whether that transfers under the Transfer of Undertakings Regulations 2006. The UK Supreme Court referred to the European Court of Justice the question whether national courts could give a more favourable interpretation to legislation than had been given by German courts.
Autoclenz Ltd v Belcher [2011] UKSC 41 is a landmark UK labour law and English contract law case decided by the Supreme Court of the United Kingdom, concerning the scope of statutory protection of rights for working individuals. It confirmed the view, also taken by the Court of Appeal, that the relative bargaining power of the parties must be taken into account when deciding whether a person counts as an employee, to get employment rights. As Lord Clarke said,
the relative bargaining power of the parties must be taken into account in deciding whether the terms of any written agreement in truth represent what was agreed and the true agreement will often have to be gleaned from all the circumstances of the case, of which the written agreement is only a part. This may be described as a purposive approach to the problem.
South African labour law regulates the relationship between employers, employees and trade unions in the Republic of South Africa.
The Employment Information Directive 1991 of 14 October 1991, also known as the "Written Statement Directive", or the "Employment Information Directive" was an EU Directive which regulates European labour law for the purpose of making workers' contracts transparent. It has been superseded by the Employment Information Directive 2019.
In law, wrongful dismissal, also called wrongful termination or wrongful discharge, is a situation in which an employee's contract of employment has been terminated by the employer, where the termination breaches one or more terms of the contract of employment, or a statute provision or rule in employment law. Laws governing wrongful dismissal vary according to the terms of the employment contract, as well as under the laws and public policies of the jurisdiction.
Uber BV v Aslam [2021] UKSC 5 is a landmark case in UK labour law and company law on employment rights. The UK Supreme Court held the transport corporation, Uber, must pay its drivers the national living wage, and at least 28 days paid holidays, from the time that drivers log onto the Uber app, and are willing and able to work. The Supreme Court decision was unanimous, and upheld the Court of Appeal, Employment Appeal Tribunal, and Employment Tribunal. The Supreme Court, and all courts below, left open whether the drivers are also employees but indicated that the criteria for employment status was fulfilled, given Uber's control over drivers.
