🚫 CALIFORNIA WARNING: What NOT to Demand
❌ DON'T demand they "stop competing" or "not work for competitors"
❌ DON'T cite or attempt to enforce void noncompete clauses
❌ DON'T demand they stop soliciting clients without trade secret evidence
❌ DON'T threaten new employer without proof of misappropriation
⚠️ SB 699 Risk: Attempting to enforce void noncompetes violates Bus. & Prof. Code § 16600.5 — exposing you to civil penalties and counterclaims.
Employee Departure Scenarios
Common Misappropriation Patterns
Scenario Red Flags Response
Competitor Move
Employee leaves for direct competitor		 Accessing unusual files before departure; downloading customer lists; copying technical documents Exit interview; forensic review; demand letter to employee and potentially new employer
Startup Launch
Employee(s) leave to start competing business		 Multiple departures at once; incorporating while still employed; soliciting clients before leaving Investigate timeline; demand letters; consider injunction if imminent launch using your secrets
Coworker Recruiting
Departed employee solicits current employees		 Employees suddenly resigning; communications between departed and current employees Remind current employees of obligations; send cease-solicitation demand if using confidential employee information
Customer Raid
Former employee solicits your customers		 Customers mention contact from former employee; business lost to competitor Demand if using confidential customer lists; may not be actionable if using general knowledge of industry contacts
Technical Theft
Engineer takes source code or designs		 Large downloads; USB/cloud uploads; code appearing in competitor products Forensic analysis; demand with technical specificity; likely need injunction
The Departure Timeline
Before Resignation
Warning Signs:
  • Unusual access to files outside normal job duties
  • Large downloads or USB/cloud transfers
  • Printing unusual volume of documents
  • Accessing after-hours or from unusual locations
  • Suddenly interested in documents they don't normally use
Resignation Notice
Immediate Actions:
  • Preserve all access logs from past 90+ days
  • Consider limiting access to sensitive systems
  • Schedule exit interview
  • Review their NDA and employment agreements
  • Identify what confidential information they had access to
Exit Interview
Cover These Points:
  • Remind of ongoing confidentiality obligations
  • Collect all company property (laptop, phone, badges, keys)
  • Obtain signed certification of return of materials
  • Ask about future employment (tactfully—don't pry aggressively)
  • Provide written summary of post-employment obligations
Departure Day
Final Steps:
  • Terminate all system access immediately
  • Revoke badge/building access
  • Forward or disable email
  • Review returned devices before wiping
  • Forensically image devices if suspicious activity detected
Post-Departure
Monitoring & Follow-Up:
  • Complete forensic analysis of access logs
  • Monitor for competitor activity using your information
  • Watch for solicitation of customers or employees
  • Send reminder letter if concerns arise
  • Escalate to demand letter or litigation if misappropriation confirmed
Don't Delay: The longer you wait after discovering misappropriation, the weaker your injunction case becomes. Courts expect urgency if the harm is truly "irreparable."
Investigating Employee Misappropriation
Digital Forensics
Evidence Source What to Look For
File Access Logs Files accessed, dates, frequency; unusual patterns before departure
Download/Copy Logs Downloads to local storage; copies to USB; cloud uploads (Dropbox, Google Drive, personal email)
Email Forwarding to personal accounts; attachments sent outside; communications with competitors
Print Logs Unusual printing volume; sensitive documents printed
VPN/Remote Access After-hours access; access from unusual locations
Device Forensics Files on returned devices; deleted files (recoverable); browser history; USB connection history
Cloud Storage Company data in personal cloud accounts accessed from work network
Preserve Before You Investigate: Before conducting any analysis, issue a litigation hold to preserve all relevant evidence. If you modify or delete data during investigation, you may face spoliation sanctions.
Common Misappropriation Evidence
  • Pre-departure download spike: Employee who normally accesses 10 files/day suddenly downloads 500 files in final week
  • USB connection: Device logs show USB drive connected and large transfers made
  • Email to personal account: Attachments sent to personal Gmail/Yahoo address
  • Cloud sync: Personal Dropbox installed on work computer with company files synced
  • After-hours access: Accessing sensitive files at 2 AM on final weekend
  • Breadth of access: Accessing files from multiple departments beyond job scope
Witness Interviews
  • Coworkers who may have observed suspicious behavior
  • IT staff who may have been asked for unusual access
  • Supervisors who can confirm what information employee had legitimate access to
  • HR regarding any prior issues or complaints
  • Customers or vendors who may have been contacted
Competitive Intelligence (Legitimate)
  • LinkedIn: New employer, new role, who they're connected to
  • Press releases: Announcements about new hires, new products
  • Patent/trademark filings: Applications listing former employee as inventor
  • Trade shows: Products or presentations that appear to use your technology
  • Customer feedback: Reports of competitor offering similar solutions
Don't Cross Lines: Don't access employee's personal accounts, intercept communications, or conduct surveillance beyond legitimate business review of company systems. Improper investigation can expose you to liability and taint your case.
California Employee Mobility Rights
Business & Professions Code § 16600: "Except as provided in this chapter, every contract by which anyone is restrained from engaging in a lawful profession, trade, or business of any kind is to that extent void." California courts interpret this BROADLY to protect employee mobility. You cannot stop employees from working for competitors—only from misappropriating your actual trade secrets.
What You CAN'T Do
Prohibited Why It's Prohibited
Non-compete agreements Void under § 16600 (with very narrow exceptions)
Prevent employee from working for competitor Violates § 16600 employee mobility rights
Prevent employee from using general skills/knowledge General knowledge belongs to employee, not trade secret
"Inevitable disclosure" injunctions California courts hostile to this doctrine—seen as backdoor non-compete
Broad non-solicitation of customers May be unenforceable if too broad—depends on specifics
Require employee to disclose new job before starting Generally unenforceable
What You CAN Do
Permitted Requirements
NDAs / Confidentiality agreements Enforceable if reasonable in scope; can't be disguised non-compete
Prevent use of actual trade secrets Must be specific confidential information, not general knowledge
Demand return of company materials Physical and electronic copies of confidential documents
Injunction for specific trade secret use Must show actual or threatened misappropriation of identified trade secrets
Non-solicitation of employees Generally enforceable if reasonable, but can't prevent former employee from hiring people who independently seek them out
Invention assignment agreements Enforceable within limits of Labor Code § 2870
The "General Knowledge" Line

Employees can use general skills, knowledge, and experience gained during employment—even if learned on your dime. This includes:

  • Industry knowledge and market understanding
  • Technical skills and methodologies
  • Management and business skills
  • Professional relationships (knowing people exists—using confidential contact details is different)
  • General understanding of how your business operates

This does NOT include:

  • Specific customer lists with pricing and purchase history
  • Proprietary source code or technical specifications
  • Detailed business strategies and financial projections
  • Secret formulas or manufacturing processes
  • Confidential vendor terms and pricing
Drafting Demands: Your demand letters must be carefully drafted to target trade secret misappropriation, not employee mobility. Demands that effectively seek to prevent someone from working in their field—even if framed as trade secret claims—may be challenged as violating § 16600 and could result in fee-shifting against you.
