The U.S. Postal Service, facing pressure from Congress to propose initiatives to ensure the agency’s long-term viability, is floating a business plan that would include significant cuts to employees’ take-home pay and benefits.

USPS included a hike to the employee contribution level for pensions in a first draft of a 10-year business plan presented to lawmakers and stakeholders, according to multiple people who were briefed on it, as well as phasing out pensions altogether for new hires in favor of a defined-contribution system only. The Postal Service is looking to cut the amount of paid time off employees receive by merging annual and sick leave and pitched a popular proposal with demonstrated bipartisan backing to require all postal retirees to enroll in Medicare as their primary insurance provider.

The mailing agency suggested it resume closures of mail processing plants, according to those briefed by management, a controversial practice it has used to reduce its vast physical footprint and shed workers. USPS stopped closing the facilities amid congressional pushback and intensifying talks for a legislative overhaul to the agency. Last year, the Postal Service inspector general found the agency realized just 5% of its projected savings from the consolidation plan.

USPS told those briefed on its plan that it was still subject to change. At a hearing in April, lawmakers grilled Postmaster General Megan Brennan on why the agency had failed to produce a 10-year business plan and indicated they would not move forward on legislative reforms USPS has said it desperately needs without first viewing the document. The details of the business plan were first reported by HuffPost.
