The Three-Day Week was one of several measures introduced in the United Kingdom by the Conservative government to conserve electricity, the generation of which was severely restricted owing to industrial action by coal miners. The effect was that from 1 January until 7 March 1974 (also the same month the 1973-74 oil crisis ended) commercial users of electricity were limited to three specified consecutive days' consumption each week and prohibited from working longer hours on those days. Services deemed essential (e.g. hospitals, supermarkets and newspaper printing presses) were exempt. Television companies were required to cease broadcasting at 10.30 pm during the crisis to conserve electricity, although the restrictions were dropped after a general election was called.
Throughout the mid-1970s, especially 1974 and 1975, the British economy was troubled by high rates of inflation. To tackle this, the government capped public sector pay rises and publicly promoted a clear capped level to the private sector. This caused unrest among trade unions as wages did not keep pace with price increases. This extended to most industries including coal mining, which provided the majority of the country's fuel and had a powerful trade union.
By the middle of 1973, the National Union of Mineworkers (NUM) – drawn from a workforce who almost wholly worked for the National Coal Board – was becoming more militant with the election of Mick McGahey as vice-president. The national conference passed resolutions for a 35% wage increase, regardless of any government guidelines, and for the election of a Labour government committed to "true socialist policy" including nationalisation of land and all key monopolies.
As inflation increased, miners' wages fell in real terms and, by October 1973, average wages were 2.3% lower than recommended by the Wilberforce Inquiry.[clarification needed] In November 1973, the national executive committee of the NUM rejected the pay offer from the NCB and held a national ballot on a strike. The vote was rejected by 143,006 to 82,631. However, an overtime ban was implemented with the aim of halving production. This action hurt the coal industry and was unpopular amongst the British media, although the Trades Union Congress supported the NUM's actions.
The Three-Day WeekEdit
To reduce electricity consumption, and thus conserve coal stocks, the prime minister, Edward Heath, announced a number of measures on 13 December 1973, including the Three-Day Work Order, which came into force at midnight on 31 December. Commercial consumption of electricity would be limited to three consecutive days each week. Heath's objectives were business continuity and survival and to avoid further inflation and a currency crisis. Rather than risk a total shutdown, working time was reduced to prolong the life of available fuel stocks. Television broadcasts were to shut-down at 10.30 pm each evening, and most pubs were closed; due to the power surges generated at 10.30 pm, the Central Electricity Generating Board argued for a staggered shutdown on BBC and ITV , alternating nightly, and this was eventually introduced. The television broadcasting restrictions were introduced on 17 December 1973, suspended for the Christmas and New Year period, and lifted on 8 February 1974.
On 24 January 1974, 81% of NUM members voted to strike, having rejected the offer of a 16.5% pay rise. In contrast to the regional divisions of other strikes, every region of the NUM voted by a majority in favour of strike action. The only area that did not was the Colliery Officials and Staff Association (COSA) section. Some administrative staff had joined another union, APEX, to distance themselves from the increasing militancy of the NUM. APEX members did not strike, which led to resentment amongst NUM members.
In the aftermath of the vote, there was speculation that the army would be used to transport coal and man power stations. McGahey called in a speech for the army to disobey orders, and either stay in the barracks or join picket lines, if they were asked to break the strike. In response, 111 Labour MPs signed a statement to condemn McGahey. He responded "You can't dig coal with bayonets."

The strike began officially on 5 February and, two days later, Heath called the February 1974 general election while the Three-Day Week was in force. His government emphasised the pay dispute with the miners and used the slogan "Who governs Britain?". Heath believed that the public sided with the Conservatives on the issues of strikes and union power.
On 21 February 1974, the government's Pay Board reported that the NUM's pay claim was within the Phase 3 system for claims and would return miners' wages to the levels recommended by the Wilberforce Enquiry in 1972.
NUM control of picketingEdit
There had been some violence on miners' picket lines during the unofficial strike of 1969 and the official strike of 1972. Aware of the damage that could be done to the Labour Party's electoral prospects by media coverage of picket-line violence, the NUM instituted strict controls over pickets. Pickets had to wear armbands saying "official picket" and had to be authorised by areas. Unlike in 1972, students were discouraged from joining miners' picket lines. Every picket line had to be authorised by the local NUM area with a chief picket to ensure that no violence took place.
Most of the media were strongly opposed to the NUM strike. An exception was the Daily Mirror, which ran an emotive campaign to support the NUM. Its edition on election day in 1974 showed hundreds of crosses on its front page to represent the miners who had died since nationalisation in 1947, accompanied by the message, "Before you use your cross, remember these crosses".
The election resulted in a hung parliament: the Conservative Party took the largest share of the vote, but lost its majority, with Labour having the most seats in the House of Commons. In the ensuing talks, Heath failed to secure enough parliamentary support from Liberal and Ulster Unionist MPs; and Harold Wilson returned to power in a minority government. The normal working week was restored on 8 March, but other restrictions on the use of electricity remained in force. A second general election was held in October 1974 cementing the Labour administration, which gained a majority of three seats.
In the campaign for the 1979 general election, after the Winter of Discontent running into that year, both main adversaries had startling graphic advertisements: Labour reminded voters of the Three-Day Week, with a poster showing a lit candle and bearing the slogan "Remember the last time the Tories said they had all the answers?" The Conservatives ran against Labour Prime Minister James Callaghan who on his arrival back from a conference in Guadeloupe played down the crisis. The Conservatives' message prevailed, and Margaret Thatcher became prime minister. Their main campaign slogan was "Labour Isn't Working".
