1. What are Trade Unions? | 什么是工会？

A trade union is a formal organisation of workers that aims to protect and improve its members’ real wages, working conditions, job security and other terms of employment. Unions use collective action, such as bargaining with employers, to achieve their goals. If negotiations fail, they may take industrial action, including strikes or work-to-rule.

工会是工人的正式组织，旨在保护和改善其成员的实际工资、工作条件、就业保障和其他雇佣条款。工会通过集体行动（例如与雇主谈判）来实现目标。如果谈判失败，他们可能采取罢工或变相怠工等产业行动。

In the WJEC IGCSE Economics specification, trade union activity is studied within the context of labour market interventions. Students must be able to illustrate and explain how union-negotiated wages can diverge from the competitive equilibrium, and consider both the microeconomic and wider economic effects.

在 WJEC IGCSE 经济大纲中，工会活动是在劳动力市场干预的背景下研究的。学生必须能够图示并解释工会谈判达成的工资如何偏离竞争均衡，并考虑其微观和更广泛的经济影响。

2. Types of Trade Unions | 工会的类型

Several types of trade union exist, each representing different groups of workers. The main categories are:

工会存在几种类型，各自代表不同的工人群体。主要类别包括：

Craft (or trade) unions: These represent workers with a particular skill or trade, such as electricians or plumbers. They often control entry into the profession.

行业工会：代表具有特定技能或手艺的工人，如电工或水管工。他们通常控制着进入该职业的渠道。

Industrial unions: These cover all workers within a particular industry, regardless of their specific role, for example the National Union of Mineworkers.

产业工会：覆盖特定产业内的所有工人，不论其具体岗位，例如矿工工会。

General unions: These represent workers from many different occupations and industries, such as Unite or GMB in the UK. They have very large, diverse memberships.

一般工会：代表来自许多不同职业和行业的工人，如英国的联合工会。其会员数量庞大且多样化。

White-collar unions: These are for professional, administrative or managerial staff, for example unions for teachers, nurses or civil servants.

白领工会：面向专业、行政或管理人员，例如教师、护士或公务员的工会。

3. Collective Bargaining | 集体谈判

Collective bargaining is the negotiation process between trade unions (representing employees) and employers or employers’ associations over pay, working hours, conditions and other employment matters. It replaces individual negotiation, giving workers greater bargaining power through solidarity.

集体谈判是工会（代表雇员）与雇主或雇主协会之间就工资、工时、工作条件及其他雇佣事宜进行的谈判过程。它取代了个体谈判，通过团结使工人拥有更强的议价能力。

If collective bargaining fails to reach an agreement, a dispute can arise. Unions may ballot their members for industrial action, which can range from an overtime ban to a full strike. The threat of disruption is often enough to bring employers back to the table.

如果集体谈判未能达成协议，就可能产生纠纷。工会可能会组织会员投票决定采取产业行动，范围从禁止加班到全面罢工。中断生产的威胁往往足以让雇主重回谈判桌。

The outcome of collective bargaining can result in a wage rate set above the market-clearing level, which then leads to the analysis of union power in the labour market using demand and supply diagrams.

集体谈判的结果可能导致工资率设定在高于市场出清水平，继而引发使用供需模型分析劳动力市场中工会力量的讨论。

4. How Trade Unions Influence Wages | 工会如何影响工资

Trade unions can push wages above the competitive equilibrium through several mechanisms:

工会可以通过若干机制将工资推至竞争均衡之上：

Restricting labour supply: By controlling entry into a profession (e.g. requiring certain qualifications or limiting apprenticeships), unions shift the supply curve of labour to the left. This raises the equilibrium wage but reduces the quantity of labour employed.

限制劳动力供给：通过控制进入某一职业（如要求特定资质或限制学徒数量），工会使劳动力供给曲线左移。这提高了均衡工资，但减少了就业的劳动力数量。

Increasing the demand for labour: Unions may try to increase the demand for their members by improving productivity through training, or by campaigning for import restrictions to boost demand for domestically produced goods. A rightward shift in labour demand increases both wages and employment.

增加劳动力需求：工会可能通过培训提高生产率以增加对其成员的需求，或通过争取进口限制来提高对国产商品的需求。劳动力需求右移会同时提高工资和就业。

Setting a minimum wage above the equilibrium: Through collective bargaining, a union can agree a wage floor with an employer that is higher than the market rate. This can operate like a minimum wage, creating a wage rigidity and potential excess supply of labour.

设定高于均衡的最低工资：通过集体谈判，工会可以与雇主达成高于市场水平的工资底线。这类似于设定最低工资，造成工资刚性并可能导致劳动力超额供给。

5. Analysis Using Labour Market Diagrams | 运用劳动力市场图示分析

In a perfectly competitive labour market, the initial equilibrium wage is Wₑ and the equilibrium employment level is Lₑ, where labour demand (DL = marginal revenue product) equals labour supply (SL).

在完全竞争的劳动力市场中，初始均衡工资为 Wₑ，均衡就业水平为 Lₑ，此时劳动力需求（DL = 边际收益产出）等于劳动力供给（SL）。

If a trade union successfully secures a wage rate W₁ > Wₑ, the quantity of labour supplied increases to Ls while the quantity of labour demanded falls to Ld. This creates an excess supply of labour equal to Ls − Ld, which represents classical unemployment. The job losses are greater the more elastic the demand for labour.

如果工会成功争取到工资率 W₁ > Wₑ，劳动力供给量将增加至 Ls，而劳动力需求量降至 Ld。这造成了 Ls − Ld 的劳动力超额供给，即古典失业。劳动力需求弹性越大，失业人数越多。

However, if the union also succeeds in shifting the labour demand curve to the right (for instance through productivity gains), the new equilibrium can occur at a higher wage and a higher employment level, reducing or eliminating the unemployment effect.

然而，如果工会也成功地使劳动力需求曲线右移（例如通过生产率提高），新的均衡可能出现在更高的工资和更高的就业水平上，从而减轻或消除失业效应。

Examiners expect you to draw and explain these diagrams, and to use elasticity concepts to evaluate the extent of the employment impact. A ‘high road’ strategy where unions boost productivity can lead to a win-win outcome.

考官期望你画出并解释这些图示，并运用弹性概念评估就业影响的程度。工会提高生产率的”高端道路”策略可以带来双赢的结果。

6. Trade Union Membership and Density | 工会会员与密度

Trade union density measures the proportion of the workforce that belongs to a union. In many developed economies, union density has declined over recent decades. For example, in the UK density fell from over 50% in the 1970s to around 23% by 2020, though public-sector membership remains higher.

工会密度衡量劳动力中属于工会的比例。近几十年来，许多发达经济体的工会密度均出现下降。例如，英国工会密度从 1970 年代的 50% 以上降至 2020 年的约 23%，但公共部门会员比例仍然较高。

Reasons for the decline include the shrinking of traditionally unionised manufacturing industries, the growth of part-time and gig-economy jobs, changes in government legislation making it harder to organise, and a rise in flexible working practices where employers communicate directly with staff.

下降的原因包括传统工会化制造业的萎缩、兼职和零工经济工作的增长、政府立法变化使组建工会更困难，以及灵活工作方式的兴起，雇主直接与员工沟通。

Trade union density is important because it affects the bargaining power of unions: a union with high density can impose greater costs on an employer during a dispute.

工会密度之所以重要，是因为它影响工会的议价能力：密度高的工会在争议期间能给雇主带来更大的成本压力。

7. Factors Affecting Trade Union Strength | 影响工会力量的因素

Several factors determine the power and effectiveness of a trade union:

若干因素决定了工会的力量与效能：

Union density and membership: A larger, more united membership gives the union more credibility in threatening disruption.

工会密度与会员数量：更大、更团结的会员基础使工会在威胁中断生产时更具可信度。

Legal framework: Laws can either protect union activities (e.g. the right to strike) or restrict them (e.g. banning secondary picketing). The UK has seen both union-friendly and restrictive legislation over the past fifty years.

法律框架：法律既可以保护工会活动（如罢工权），也可以限制它们（如禁止次级纠察线）。过去五十年间，英国经历了亲工会和限制工会两种类型的立法。

Economic conditions: In a recession with high unemployment, union power diminishes because workers are more afraid of losing their jobs and there is a large pool of substitute labour. In a tight labour market, union power increases.

经济状况：在高失业率的衰退期，工会力量减弱，因为工人更害怕失去工作，而且有大量可替代劳动力。在劳动力市场趋紧时，工会力量增强。

Globalisation and technology: Firms can outsource production to countries with cheaper, non-unionised labour, which weakens domestic unions. Automation can also replace unionised workers, reducing their bargaining leverage.

全球化和技术：企业可以将生产外包到拥有更廉价、无工会劳动力的国家，从而削弱国内工会。自动化也可以取代工会化工人，降低其谈判筹码。

Public support and political climate: Unions with broad public sympathy and a supportive government can achieve more, while a hostile political environment limits their influence.

公众支持和政治氛围：获得广泛公众同情和政府支持的工会能取得更大成果，而对立的政经环境则限制其影响力。

8. Advantages and Disadvantages of Trade Unions | 工会的优缺点

It is essential to evaluate both sides of trade union activity for high-mark exam questions.

在考试中获得高分，必须对工会活动的两面进行评价。

Advantages:

优点：

Higher wages and better conditions: Unions can raise members’ real pay, reduce working hours and improve workplace safety, boosting living standards and morale.

更高的工资和更好的条件：工会可以提高成员的实际工资，缩短工时并改善工作场所安全，提高生活水平和士气。

Reduce income inequality: By compressing the wage distribution between the lowest and highest paid workers, unions can help distribute income more evenly.

减少收入不平等：通过缩小最低与最高薪酬工人之间的工资差距，工会可以帮助更均匀地分配收入。

Voice and representation: Unions provide a collective voice, protecting workers from unfair dismissal and discrimination, and ensuring that employers address grievances.

发声与代表：工会提供集体发声渠道，保护工人免受不公平解雇和歧视，并确保雇主处理申诉。

Productivity gains: Where unions cooperate with management on training and work organisation, productivity can rise, benefitting both the firm and workers.

生产率提升：当工会与管理层就培训和工作组织进行合作时，生产率可以提升，使企业和工人都受益。

Disadvantages:

缺点：

Unemployment risk: Pushing wages above the equilibrium may cause firms to shed labour, especially where demand is wage-elastic. The jobless are often those least able to afford it.

失业风险：将工资推至均衡之上可能导致企业裁员，尤其在劳动力需求富有工资弹性时。失业者往往是最承受不起的人。

Cost-push inflation: If widespread union power pushes up wages across the economy without corresponding productivity gains, firms may pass on higher costs as higher prices, fuelling inflation.

成本推动型通胀：若大范围的工会力量在全经济中推高工资而没有相应的生产率增长，企业可能将成本上升转嫁为更高的价格，推升通胀。

Lost competitiveness: Higher labour costs can make domestic firms less competitive internationally, potentially leading to a loss of exports and jobs.

竞争力丧失：更高的劳动力成本会降低国内企业的国际竞争力，可能导致出口和就业岗位的减少。

Industrial conflict: Strikes and other action disrupt production, damage customer relationships and can lead to permanent job losses. Days lost due to strikes are a clear economic cost.

产业冲突：罢工等行动打乱生产，损害客户关系，并可能导致永久性失业。因罢工损失的工作日是一项明显的经济成本。

Inefficiency: Seniority-based pay and restrictive practices can reduce labour market flexibility, making it harder for firms to adapt to changing market conditions.

低效率：以资历为基础的薪酬和限制性做法会降低劳动力市场的灵活性，使企业更难适应不断变化的市场条件。

9. Government Policies and Trade Unions | 政府政策与工会

Government intervention can dramatically shape the legal environment in which unions operate. In the UK during the 1980s, Conservative governments introduced legislation that required pre-strike ballots, abolished closed shops (where union membership was compulsory), and made secondary action unlawful. These reforms significantly reduced union power and membership.
