Kim Leffert has an extensive litigation practice. A significant and growing part of her work involves electronic discovery issues. Kim has substantial experience assisting clients with the preservation, collection, review and production of electronic documents in litigation. She also helps clients prepare document retention policies and procedures and records management programs, as well as develop electronic discovery programs.

Kim's other primary emphasis is on labor and employment disputes. She has bench and jury trial experience in federal and state court actions involving state common law theories (breach of contract and tort) and wage-and-hour issues, as well as the defense of employers in a wide variety of EEO and Section 301 actions. She has argued cases before the Fourth and Seventh Circuit Court of Appeals on disability discrimination and sexual harassment. In administrative proceedings, Kim represents employers before the National Labor Relations Board (unfair labor practice claims, unit determinations, election proceedings) and the EEOC and state human rights agencies (discrimination charges and hearings). She has also participated in court and agency sponsored formal mediation programs and represents employers in labor arbitrations.

Kim also counsels employers on proactive strategies to avoid litigation and disputes. She helps clients craft appropriate handbooks and policies (including preservation of employment-at-will rights and compliance with FMLA, veterans rights, state protective laws) and offers guidance on WARN compliance regarding plant closures. In the area of discrimination, Kim assists clients with EEO issues in both individual and collective employment decisions, defends against discrimination claims (Title VII, ADA, ADEA and state/local equivalents), prepares affirmative action plans, represents employers during compliance reviews and in the resulting administrative proceedings, and presents training programs on various EEO topics.

Kim's employment law counseling addresses a variety of other employer concerns. She advises management on collective bargaining strategies and contract interpretation issues. When necessary, she investigates alleged executive wrongdoing. And when mergers, acquisitions and other business transactions arise, she helps clients conduct employment-related due diligence, negotiates contract provisions, and drafts employment-related sections of transaction documents.

Finally, Kim has made a strong impression on clients, one of whom commented in Chambers USA 2010, She has done an excellent job and has been helpful and pleasant to work with; she is experienced, confident and very thorough.

Kim joined Mayer Brown in 1994 after nearly a decade with two other Chicago law firms.
