Spain's part-time workforce hits record high, but pension impact looms

Spain's employment landscape has shifted dramatically, with over 3 million people now working part-time, a figure that represents 14% of the country's occupied population as of 2026. This trend has been driven by the need for workers to balance professional and personal responsibilities. However, the long-term implications for pension plans cannot be ignored.

Part-time work's pension penalty

While part-time employment can help individuals remain in the job market, it also contributes to lower pension benefits in retirement. Recent reforms have softened the impact, but the issue remains. The key factor is not just the length of time worked, but also the amount contributed. In 2023, Spain equalized the counting of part-time days, with one partial day counting as a full day for pension purposes. However, the final pension sum still hinges on real, proportionally lower contributions.

A contract at 50% can cut a pension by up to 50% compared to an equivalent full-time schedule, although formulas exist to mitigate this loss. For instance, someone with 20 years of part-time work would be counted as having 20 full years, but their pension could be 30-50% lower than a colleague with the same time served but in full-time employment.

The double-edged sword of part-time work

Part-time employment has a strong gender aspect, with 73% of part-time workers in Spain being women. This is reflected in the fact that, on average, women receive a 30% lower pension than men. While the impact cannot be fully eliminated, strategies do exist to reduce it.

One approach is to increase contributions in the final years of a working career, either by moving to full-time or boosting salaries. Since the calculation typically focuses on the last 25 years, this adjustment can have a notable effect. Another option is to prolong one's working life, as this allows for a greater percentage of the pension benefit base to be applied, potentially nearing 100%. The Social Security system also offers various formulas that delay retirement in exchange for pension incentives.

Further, special contracts with Social Security can cover the difference between actual and full-time contributions with a monthly premium (around 25-30% of the maximum base). Private pension plans can also help supplement income in retirement. Additionally, the gender gap pension supplement provides a contributive payment per child, currently 35.90 euros per month per offspring.
