Part-time pensions: the plan detail that can matter more than a pay rise
Part-time employees may discover that their pension saving does not follow salary proportionately. A company seeking a fair benefits package should examine the insured salary rather than assuming that a modest pay increase fixes the issue. Coordination rules are central to that discussion.

The business question
Part-time employees may discover that their pension saving does not follow salary proportionately. A company seeking a fair benefits package should examine the insured salary rather than assuming that a modest pay increase fixes the issue. Coordination rules are central to that discussion.
Understand the mechanism
The compulsory system uses an entry threshold and coordinated salary. Funds can provide more generous treatment under their rules, including different approaches to coordination for part-time work. The rejection of the 2024 reform should not be presented as enactment of the proposed improvements.
Hypothetical business case
A fictional company employs two people in similar roles at different activity rates. The employer requests parallel pension illustrations showing annual salary, insured salary, savings and risk benefits. Comparing those lines reveals whether the plan’s approach to part-time work produces an outcome the company wants to change.
Decisions before you commit
Ask the fund for the exact coordination formula and test it at several activity rates. Price any improvement across the entire eligible workforce, including employer contributions. Avoid promising an individual exception without checking plan rules, collective design requirements and implementation conditions.
Your evidence pack
Prepare salary and activity-rate data, current pension certificates and proposed plan provisions. Explain the difference between gross salary and insured pension salary in recruitment material. The useful decision is a documented design choice, not a slogan claiming equal pension protection for everyone.
Stress-test the decision
Compare employee outcomes at several activity rates using the same full-time salary benchmark. Look at the difference between take-home pay today and retirement savings or risk protection, rather than assuming more insured salary is cost-free. A more generous design can raise contributions for employees as well as the employer. Explain that trade-off and ask the fund how benefits are affected. Review the entire eligible population so a change intended to help one worker does not unintentionally create another imbalance. The final plan should have an understandable rationale that can be communicated without promising identical outcomes.
Trade-offs and implementation
Multiple employment deserves a separate conversation. An employee earning income from several employers may not have the same affiliation position as someone receiving the same total salary from one company. The fund or competent specialist should explain available options; the HR team should not add incomes informally and declare the matter settled.
A part-time improvement also has distributional effects within the workforce. Compare who contributes more, who receives more insured benefits and whether lower-paid workers can support the additional deduction. Seek a design that can be explained consistently, rather than negotiating confidential exceptions by recruitment bargaining power. Test changes in activity rate during the year and confirm how the new salary basis is recorded. The employer’s contribution may make the improvement attractive, but today’s available income still matters to employees. Present both perspectives so the decision addresses protection and affordability, not simply an impressive projected retirement figure.
