Sheldon began his legal career as a general litigator in a small firm and has been practicing labor and employment law since the early 1970s. During the 1970s, he pioneered the specialty of labor and employment law in Delaware and along with Barry Willoughby began Young Conaway's Employment Law Section in 1981.

His prominence in the field has been recognized repeatedly. Chambers USA - America's Leading Lawyers for Business has ranked him first in its ratings of Delaware Employment Lawyers representing Management. He was selected by Who's Who Legal "as being among the world's pre-eminent Management Labour & Employment lawyers." He has also been listed in The Best Lawyers In America® for over thirty years and has been recognized by Delaware Super Lawyers®.

At the 2004 American Bar Association Convention, Sheldon became the first Delaware lawyer inducted as a Fellow of the College of Labor and Employment Lawyers. Election as a Fellow is described as "the highest recognition by one's colleagues of sustained outstanding performance in the profession, exemplifying integrity, dedication and excellence." He has served on the College's Third Circuit Credentials Committee.

Sheldon retired as an equity partner effective January 1, 2012 and is “Of Counsel” to the Firm. In addition to performing significant amounts of pro bono work, he conducts an active mediation and arbitration practice in the area of labor and employment law, and has testified as an expert witness on Delaware law. See Lambert v. Ultramar ltee, 2013 QCCS 388 (Feb. 24, 2013).

Sheldon was approved unanimously by the Delaware Senate, and on June 28, 2023, he was reappointed to the MERB for a third term by Governor John C. Carney.
