Sean Beiter, a partner of the firm, focuses his practice in the area of traditional labor law for public sector and private sector employers in the blue collar, white collar, health care, printing, and public safety settings, including representation in collective bargaining negotiations, contract administration, and grievance arbitration. Sean has also represented many employers in disciplinary procedures and contract dispute arbitrations as well as before compulsory interest arbitration proceedings.

Sean's practice also includes the representation of employers in both state and federal court, before the National Labor Relations Board, the Public Employment Relations Board, the Equal Employment Opportunity Commission, the State Division of Human Rights and the Department of Labor.

His court litigation proceedings include a duty of fair representation jury trial, numerous special proceedings under Articles 75 and 78 of the CPLR, injunction actions, and claims of employment discrimination.

Sean's litigation successes include two victories at the New York State Court of Appeals: In the Matter of Chautauqua County v CSEA, 8 N.Y.3d 513 (2007) and In the Matter of the County of Erie and Erie County Sheriff v PERB, et al., 12 N.Y.3d 72 (2009). He also successfully represented the City of Buffalo in wage freeze litigation involving both the Buffalo Police Benevolent Association and the Buffalo Professional Fire Fighters Association. Most recently, in July 2015, he obtained a defense verdict that fully vindicated the employer in a jury trial on allegations of age discrimination under the Age Discrimination in Employment Act in the United States District Court for the Western District of New York.

His accomplishments in collective bargaining include the representation of the City of Buffalo in negotiations with the Buffalo Police Benevolent Association for one-officer cars. He has also represented the Board of Education of the City of Buffalo in negotiations for a Project Labor Agreement for the construction of the William R. Grabiarz School of Excellence and the Niagara Frontier Transportation Authority in negotiations for the construction and expansion of the Buffalo Niagara International Airport.

Sean routinely earns the recognition of his peers in the legal field, and has consecutively been listed by The Best Lawyers in America for the past decade. In 2015, he was named Buffalo's Labor Law — Management Lawyer of the Year; only a single lawyer in each practice area in a given location earns the distinction. He has also been named to the Upstate New York Super Lawyers list each year since 2012.
