If you participate in the upcoming general strike on November 11 (11N), your Social Security contributions for that day will be affected, and it could impact your future pension. The strike, called by tenant unions over the housing crisis and supported by major unions like CCOO and UGT to demand wage improvements, raises important questions about how a strike day affects your retirement contributions.
What Happens to Your Social Security Contributions on a Strike Day?
When you exercise your constitutional right to strike, you are not removed from Social Security registration; you remain in a situation of "alta" (registered). However, as economic journalist José María Camarero warned on COPE, that does not mean you will contribute for that day. In other words, the day of the strike is not counted as a contribution day.
This is because contributions are tied to actual work and wages. If you don't work and don't receive a salary for that day, there is no contribution base. Therefore, the day is not counted toward your contribution record.

How Does a Strike Day Affect Your Future Pension?
Your pension is calculated based on your contribution period and contribution bases. Specifically, the number of days you have contributed determines the percentage of your regulatory base you receive. A strike day does not count as a contributed day, so it could reduce your total contribution days.
However, the impact of a single day is minimal. Pensions are calculated by days, not years or months, so one day less may not significantly alter your pension amount. But if you are close to a threshold (e.g., 15 years for minimum pension or 35 years for 100% of the base), it could matter.
Who Is Affected by the 11N Strike?
The 11N strike is a general strike, so it affects all workers who choose to participate. However, participation is voluntary. If you decide to strike, you should be aware of the consequences on your contributions and pension.
It's also important to note that the strike is occurring in a pre-election period, which adds political significance. The outcome and impact may vary depending on the sector and the individual's employment situation.

Earlier coverage in NHS Consultants Strike: Two-Day Walkout in November 2025 shows how the argument developed.
What Should You Consider Before Joining the Strike?
Before joining the strike, consider your personal financial situation and your retirement goals. If you are close to retirement or have a short contribution history, a missing day might have a slight effect. Otherwise, the impact is likely negligible.

Also, remember that collective agreements or company policies may offer additional protections or consequences.

FAQ
Does a strike day count toward my pension?
No, a strike day is not considered a contributed day for pension purposes because you are not working and not receiving a salary, so no contributions are made.
Am I still registered with Social Security during a strike?
Yes, you remain in a situation of "alta" (registered) with Social Security, but you do not contribute for that day.
How much does one strike day affect my pension?
The impact is usually minimal, as pensions are calculated over many years. However, if you are close to a contribution threshold, it could slightly reduce your pension percentage.
Can I make up for the lost contribution day?
In general, you cannot make up for a lost contribution day due to a strike. However, you might be able to sign a special agreement (convenio especial) to contribute voluntarily, but this comes with additional costs.
