The "Start Applying Labor Transparency Act," or SALT Act, amends the Labor-Management Reporting and Disclosure Act of 1959 to significantly expand reporting requirements for certain labor-related financial arrangements. Its primary goal is to increase transparency regarding payments and agreements intended to influence employees' decisions about organizing and collective bargaining. Specifically, the bill requires labor organizations to report any payments or loans made to employees (outside their own organization) for the purpose of persuading other employees regarding their organizing rights, unless these payments were previously disclosed. It also mandates reporting of agreements with labor relations consultants or independent contractors engaged in similar persuasive activities, or in supplying information about labor disputes, along with any payments made under such arrangements. These reports must detail the payments, recipients, circumstances, and any targeted employers. Furthermore, the legislation introduces new reporting obligations for individuals or consultants who receive payments to seek employment with a third party, where the objective is to persuade that third party's employees regarding unionization or to gather information during a labor dispute. These individuals must file an initial report within thirty days of the agreement and subsequent annual reports detailing receipts and disbursements related to these services. The Secretary of Labor is directed to issue necessary regulations within six months of the Act's enactment to implement these new requirements.
