A tradesperson or tradesman/tradeswoman is a skilled worker that specialises in a particular craft or occupation. Tradespeople (tradesmen/women) usually gain their skills through work experience, on-the-job training, an apprenticeship program or formal education, or some mix of these methods.
As opposed to a master craftsman or an artisan, a tradesperson (tradesman/tradeswoman) is not necessarily restricted to manual work.
A white-collar worker is a person who performs knowledge-based, aptitude-based, managerial, or administrative work generally performed in an office or similar setting. White-collar workers include job paths related to banking, finance, compliance, legal, risk management, internal audit, data privacy, cybersecurity, insurance, government, consulting, academia, accountancy, business and executive management, customer support, design, economics, science, technology, engineering, market research, human resources, operations research, marketing, public relations, real estate, information technology, networking, healthcare, architecture, and research and development.
In contrast, blue-collar workers perform manual labor or work in skilled trades; pink-collar workers work in care, health care, social work, or teaching; green-collar workers specifically work in the environmental sector; and grey-collar jobs combine manual labor and skilled trades with non-manual or managerial duties.
Historically, a master craftsman or master tradesman (sometimes called only master or grandmaster) was a member of a guild. The title survives as the highest professional qualification in craft industries.
In the European guild system, only masters and journeymen were allowed to be members of the guild. An aspiring master would have to pass through the career chain from apprentice to journeyman before he could be elected to become a master craftsman. He would then have to produce a sum of money and a masterpiece before he could actually join the guild. If the masterpiece was not accepted by the masters, he was prohibited to join the guild and possibly remained a journeyman for the rest of his life.
A machinist is a tradesperson or trained professional who operates machine tools, and has the ability to set up tools such as milling machines, grinders, lathes, and drilling machines.
A competent machinist will generally have a strong mechanical aptitude, the ability to correctly use precision measuring instruments and to interpret blueprints, and a working knowledge of the proper parameters required for successfully utilizing the various tools commonly used in machining operations. CNC (computer numerical control) comprises one of the most recent advances in manufacturing, in which a machinist uses specialized software to generate programmatic instructions (most commonly G-code) which are in turn interpreted by the machine to make components for a wide variety of industries. CNC programming is a skilled position which requires knowledge of math, speeds and feeds, machine tooling, work holding, and the different ways various materials react to stress and heat in the machining process.
A house painter and decorator is a tradesperson responsible for the painting and decorating of buildings, and is also known as a decorator, or house painter. The purpose of painting is to improve the appearance of a building and to protect it from damage by water, corrosion, insects and mould. House painting can also be a form of artistic and/or cultural expression such as Ndebele house painting.
A butcher is a skilled tradesperson who specialises in meatcutting, breaking down animal carcasses into primal cuts, preparation and retailing of meat, and sometimes slaughtering animals, or participates within any combination of these tasks. They may prepare standard cuts of meat and poultry for sale in retail or wholesale food establishments. A butcher may be employed by supermarkets, grocery stores, butcher shops and fish markets, slaughter houses, or may be self-employed.
Butchery is an ancient trade, whose duties may date back to the domestication of livestock; its practitioners formed guilds in England as far back as 1272. Since the 20th century, many countries and local jurisdictions offer trade certifications for butchers in order to ensure quality, safety, and health standards but not all butchers have formal certification or training. Trade qualification in English-speaking countries is often earned through an apprenticeship although some training organisations also certify their students. In Canada, once a butcher is trade qualified, they can learn to become a master butcher (Fleishmaster).
Mechanical, Electrical, and Plumbing (MEP) refers to the installation of services which provide a functional and comfortable space for the building occupants. In residential and commercial buildings, these elements are often designed by specialized MEP engineers. MEP's design is important for planning, decision-making, accurate documentation, performance- and cost-estimation, construction, and operating/maintaining the resulting facilities.
MEP specifically encompasses the in-depth design and selection of these systems, as opposed to a tradesperson simply installing equipment. For example, a plumber may select and install a commercial hot water system based on common practice and regulatory codes. A team of MEP engineers will research the best design according to the principles of engineering, and supply installers with the specifications they develop. As a result, engineers working in the MEP field must understand a broad range of disciplines, including dynamics, mechanics, fluids, thermodynamics, heat transfer, chemistry, electricity, and computers. Because MEP designs directly influence system sizing and component selection, the mechanical estimating process plays a key role in calculating quantities, assessing cost impacts, and ensuring that engineered solutions remain feasible within project budgets.
A chef is a professional cook and tradesperson who is proficient in all aspects of food preparation, often focusing on a particular cuisine. The word "chef" is derived from the term chef de cuisine (French pronunciation: [ʃɛf də kɥizin]), the director or head of a kitchen. Chefs can receive formal training from an institution, as well as by apprenticing with an experienced chef.
In modern kitchens, chefs often manage both culinary creativity and business operations, including budgeting, inventory systems, and team training.
A glazier is a tradesperson responsible for cutting, installing, and removing glass (and materials used as substitutes for glass, such as some plastics). They also refer to blueprints to figure out the size, shape, and location of the glass in the building. They may have to consider the type and size of scaffolding they need to stand on to fit and install the glass. Glaziers may work with glass in various surfaces and settings, such as cutting and installing windows, doors, shower doors, skylights, storefronts, display cases, mirrors, facades, interior walls, ceilings, and tabletops.
