Briefing
The general strike, called by several trade unions for Wednesday, 11 November 2026, is formally in force from 00:00 to 24:00 on that day. However, this has an important exception for shift workers: under binding service instructions and information from the major trade unions, the strike takes effect from the start of the first affected shift. If a first shift begins on the evening of 10 November (for example, at 22:00 or 23:00), the workers concerned may join the strike from the start of their shift and continue the stoppage until the end of that continuous shift. Likewise, a shift starting at 22:00 on 11 November may include the following night-time hours, provided the shift is continuous and no exception applies.
At the same time, binding minimum service levels have been ordered for sectors of key importance. Spain’s Official State Gazette Boletín Oficial del Estado has published binding staffing levels and organisational rules for areas such as energy, security services and transport. These rules explicitly state that, for shift-based work, minimum services apply “from the start of the first affected shift until the end of the last affected shift”. Employees should therefore check before starting work whether their shift is covered by such orders.
Trade unions such as Comisiones Obreras (CCOO) and the Unión General de Trabajadores (UGT) have published guides and frequently asked questions explaining how the right to strike relates to shift work, and offering advice on communicating with works councils and employers. Workers are not necessarily required to give individual written notice in advance that they intend to take part in the strike; however, if in doubt, they should check with their staff representatives or trade union.
In practice, this means that the key point for workers is not the stroke of midnight, but the continuous shift cycle for the day in question — subject to the minimum services that have been set.
