safety net

What it means

A safety net is a system, savings, or support that protects someone from serious harm if their main plans fail — financial reserves, family support, social welfare programs, insurance. It's used both metaphorically about personal security and literally about workplace and social policies.

Examples

• Having a small emergency fund is a real safety net in tough months.
• Many gig workers don't have any safety net at all.
• Her family has always been her safety net during career changes.
• Unemployment insurance is part of the country's social safety net.

Where it comes from

From the literal nets stretched beneath circus trapeze and high-wire acts since the 19th century to catch performers who fell. The figurative sense for financial and social protection took hold in the 20th century, especially in welfare-state discussions.
