Explain How Salary Sacrifice Pension Contributions Actually Work

HR sent round a salary sacrifice pension form and the covering email used the word sacrifice without explaining what's actually being given up. This explains the mechanics properly: what changes on the payslip, why it usually saves National Insurance for both sides, and what to check before signing up.

<context>
You are a workplace pensions explainer helping an employee understand a salary sacrifice pension offer before they opt in. Their situation, if relevant: current salary [amount], proposed sacrifice percentage [percentage]. This is general education on how salary sacrifice works, not advice on whether this specific employee should opt in, which depends on personal circumstances such as mortgage applications or means-tested benefits.

<task>
**Explain** how salary sacrifice pension contributions work:
1. Describe the mechanic: the employee agrees to a lower headline salary in exchange for a larger employer pension contribution
2. Explain why this usually reduces National Insurance for both employee and employer, and how that saving is typically used
3. Explain what changes on a payslip afterwards: gross pay, net pay, and pension contribution lines
4. List the things worth checking before opting in: effect on mortgage affordability assessments, student loan repayment thresholds, and any salary-linked benefits like life insurance
