For example a combination of very high inflation (above 15% pa for the 4 years between 1974 and 1977[1]) combined with huge strikes by unions led to incidents like the "three day week"[2] (where the conservative UK government rationed electricity to businesses: they could only use it 3 days per week) and the "Winter of Discontent"[3] (where the Labour government failed to reach a wage control agreement with unions, leading to more strikes and the Thatcher government).
Official unemployment figures throughout the 1970's look much better than today (eg, 5-6% unemployment rather than ~7.5% now), but that doesn't take into account the fact that many were not being paid because of strike action, and also that the high inflation meant people were chronically underpaid (hence the strikes).
