Six-hour day

Six-hour day is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Six-hour day rather than just read about it. In short: The six-hour day is a schedule by which the employees or other members of an institution (which may also be, for example, a school) spend six hours contributing. This is in contrast to the widespread eight-hour day, or any other time arrangement.

Key takeaways

Six-hour day belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Six-hour day to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Six-hour day from memory before moving on to harder problems.

Reference excerpt

The six-hour day is a schedule by which the employees or other members of an institution (which may also be, for example, a school) spend six hours contributing. This is in contrast to the widespread eight-hour day, or any other time arrangement. It has also been proposed as an alternative or addition to the four-day week, another proposed way to reduce working time.

By country

Australia In Australia, the six-hour day and four-day week is supported by the Australian Greens.

Finland In 2020, the Finnish Prime Minister Sanna Marin advocated for a change towards implementing a six-hour working day. The result of a Finnish study showed positive effects. The Communist Party of Finland is advocating for six-hour working day too.

Italy In Italy, the public sector used to have a schedule of 6 hours a day for 6 days a week, i.e. since 8 a.m. to 2 p.m. Monday to Saturday. Public employees used to be paid less than their private colleagues, as they worked 36 hours per week instead of 40. When, starting in the 1980s, pressure increased for a 'long week-end', meaning a free Saturday, in most sectors the 6 hours of Saturdays were moved either by extending ending time at 3:12 p.m. or, most often, to two working afternoons of 3 hours each. This solution also prevents public employees to have a second job, that was previously considered acceptable. Present-day Communist Party (Italy) advocates for a widespread six-hour workday. Their electoral result for last parliament elections, however, has been as low as 0.09%.

Norway The Red Party (Norway) has advocated for a six-hour workday.

Sweden The 6 hour workday has been subject to reoccurring debate since the early 70's after the prominent sociologist and politician Alva Myrdal proposed to implement it to Sveriges socialdemokratiska kvinnoförbund. Today there are more than a few examples of companies which already have a 6 hour workday in Sweden, and the notion of a trend towards a six-hour workday has also been mentioned. Since 2002 there is a Toyota car mechanic with a six hour workday in the small town of Mölndal. This reduction from eight to six hour shifts led to higher profitability and was implemented without any decrease in wages. According to Martin Banck who manages the shop "[our employees] have more energy. [They're] more alert. More efficient. I promise: you perform 20-30% more in six hours than eight." Several small-scale implementations of the concept have been trialed in Sweden, including the private and public sectors. In Gothenburg, an experiment with 70 nurses over 18 months found decreases in sick leave, better self-reported health as well as an increase in productivity, with a cost of 1.3 million USD. Two major parties support cutting the working hours in Sweden as of 2022. The party Vänsterpartiet (The Left Party) is advocating a 6 hour working day without decreased pay. Miljöpartiet de gröna (The Green Party) has the goal of a 30 hour workweek. Other parties advocating for 6 hour working day are: the Communist Party of Sweden and the Communist Party (Sweden). According to a survey done by Sifo in 2022 more than half of those surveyed would rather work fewer hours than get a pay raise. This tendency was stronger among surveyed women and those who self-reported as being likely to vote for Vänsterpartiet, Socialdemokraterna, or Miljöpartiet. The majority of Swedes are in favour of shorter working weeks, with the greatest support from women and people who are engaged in blue-collar jobs.

Switzerland The Swiss Party of Labour advocates for the introduction of a reduced working day (even though they ask for 35 hours, not 30).

Worked examples

Example 1 — a first encounter with Six-hour day

Start with the simplest possible case. Write down what Six-hour day claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Six-hour day before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Six-hour day ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Six-hour day

In research: Six-hour day appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Six-hour day in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Six-hour day is common in secondary-school and first-year university syllabi. It links to neighbouring topics Labor rights, Working time, so understanding it makes those chapters shorter.
In everyday life: Look for Six-hour day outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
