The phrase 'let-alone policy' refers to a policy of non-intervention or non-interference, which is essentially a hands-off approach. There are several synonyms for this phrase, including laissez-faire, non-interventionism, non-interference, a softly-softly approach, a hands-off policy, a non-involvement policy, or a non-interfering policy. These terms are frequently used in political and business contexts when describing policies or approaches to governance. For example, a government may adopt a let-alone policy in a particular industry, which means that they will not intervene or regulate that industry excessively. Similarly, a company may adopt a laissez-faire approach to leadership, allowing their employees to work independently with minimal supervision.
