How can an employer protect themselves when an employee is fired?

A business will always deal with employee turnover, whether employees leave for a change of scenery, circumstances or even a career change.

Do your staff have access to too many accounts or data they shouldn't?

  • Social Media Accounts

  • Bank Accounts

  • CRM System

  • Credit card/Accounts/Payment details

As an employer, you should consider reviewing which employees have access to these accounts and systems annually. Then, remove any employees who have left and terminate access from employees you believe shouldn't have access to these accounts or sensitive company details.


Suppose your business found that an employee had been downloading lists of sales prospects with contact details from your CRM system and then sending these files to a local competitor. What would you do next?

  1. Lock and suspend any activity on this employee's accounts

  2. Investigate the employee's performance to confirm suspicions and attain evidence of wrongdoing

  3. The employer should review any account access and data of the employee

    1. Employers should review other employees' account access and data so this isn't repeated.

    2. Revoke access where needed

  4. If necessary, consider alerting other team members that the person has left the organisation to avoid them sharing information unwittingly. Ensure they're aware and alert in knowing to report anything suspicious.
