Short answer
Semi-retirement can shrink the gap before full retirement.
Semi-retirement usually means work income continues while the household starts living more like retirement. The plan still needs spending, taxes, health coverage, Social Security timing, and withdrawals in one place.

What you actually came to find out
Plain answers first. Sources stay below for checking details.
What is it?
A transition period where some work income continues and retirement life starts partly.
What does it change?
It can reduce withdrawals, delay Social Security, and keep benefits or health coverage in place.
What can complicate it?
Taxes, earnings-test rules, benefits, employer coverage, and irregular income.
What is the plan test?
Compare full retirement with the part-time income version.
Part-time income
Gap reducer
Continuing income can reduce the amount savings must cover.
Source trail: Morningstar
Social Security
Timing
SSA estimates and claiming age affect the income line.
Earnings test
Before FRA
SSA earnings-test amounts can matter if benefits begin before full retirement age while work continues.
Source trail: SSA.gov
Health coverage
Job link
Employer coverage, marketplace coverage, and Medicare timing can shape the semi-retirement bridge.
Source trail: HealthCare.gov, Medicare.gov
The clean question is whether part-time income lowers the draw enough to make the road stronger while still giving the household the life change it wants.
Neutral landscape
The shape of the question
The income source matters first because semi-retirement is about reducing the gap with work income.
Source trail: Morningstar
SSA sources matter because claiming age and the earnings test can both enter when work continues.
Health coverage sources matter because employer coverage can be a large reason people step down instead of stop.
Source trail: HealthCare.gov, Medicare.gov
IRS tax sources matter because part-time work and withdrawals can land in the same tax year.
Source trail: IRS: Publication 590-B: Distributions from Individual Retirement Arrangements, IRS: Tax Inflation Adjustments
