Experienced advising on the full range of employment disputes, Quinn has particularly deep expertise advising on:

Wage and hour litigation and class actions
.  Quinn has extensive experience advising on individual lawsuits as well as class action disputes between employers and employees regarding compensation, hours worked, and related workplace issues. She has handled cases involving allegations of unpaid wages, overtime violations, minimum wage violations, meal and rest break violations, misclassification of employees as exempt from overtime, service charges related to tipping in the restaurant industry, and drive time allowances for employees using employer-provided vehicles.

Non-compete and restrictive covenants, employment and severance agreements, and related litigation.  Quinn advises employers on entering into agreements designed to prevent employees from engaging in competitive activities after leaving their job and, when necessary, she represents employers in litigating non-compete and restrictive covenant disputes. She also advises executives regarding such agreements, as well as general employment, compensation, and severance agreements.

Employment discrimination.  Quinn defends employers in lawsuits brought by employees claiming discrimination, harassment, or retaliation, including alleged violations of the Washington Law Against Discrimination (WLAD), Title VII of the Civil Rights Act, the Americans with Disabilities Act (ADA), the Age Discrimination in Employment Act (ADEA), and other federal and state laws.

Grievance arbitrations.  Quinn represents employers with unionized workplaces in grievance proceedings.

She also teaches employment law as an adjunct professor at Seattle University School of Law.

Outside of the office, you can find Quinn chasing her daughter around local playgrounds, wandering around Capitol Hill, and seeking out spicy Chinese food.
