Greg Ossi helps employers address human resource issues with practical solutions by focusing on all aspects of labor and employee benefits law.

Greg has counseled employers in dealing with union organizing, unfair labor practice charges, and labor issues arising from mergers, acquisitions, and bankruptcy. Greg has also counseled employers on employee benefits. He has arbitrated issues in both labor and employee benefit matters and has litigated labor and ERISA cases in federal courts in the District of Columbia, Illinois, Kentucky, and Virginia. Greg has extensive experience in bargaining for and drafting retirement and healthcare plans pursuant to collective bargaining agreements. Greg has represented companies as special labor counsel and as special benefits counsel in addressing collectively bargained obligations, multiemployer pension liability, and retiree health benefits under Sections 1113 and 1114 of the Bankruptcy Code.

Greg also has particular experience with and understanding of multiemployer pension and health plan issues. Greg has represented employers across a wide spectrum of industries in evaluating and disputing withdrawal liability. He has given numerous presentations across the country on various issues that arise from participating in a multiemployer pension plan, including the requirements of the Pension Protection Act and the Multiemployer Pension Reform Act.

Greg's depth of understanding of both labor and benefits law issues allows clients maximum flexibility to solve pension and health benefit issues. In confronting rising medical costs, Greg has worked with medical providers and unions to create drug formularies that reduce prescription drug costs for employers while still providing a valuable benefit to employees. Greg was also a certified public accountant prior to becoming an attorney.
