What should a badge holder do if they change employers?

When a badge holder changes employers, the most appropriate action to take is to notify the airport authority to update their badge information. This process ensures that the individual's security credentials remain valid and accurate, reflecting their current employment status. By informing the airport authority, the badge holder helps maintain the integrity of security procedures at the airport, which rely on accurate information about who has access to secure areas.

Updating badge information is crucial because it allows the airport authority to keep track of which individuals are authorized to work in specific areas and to ensure that all personnel comply with security regulations. This is particularly relevant in environments like airports, where security is of utmost importance.

The other options do not align with best practices. For instance, ignoring the badge and continuing to work undermines security protocols and could lead to serious repercussions. Returning the badge to the airport authority is a step in the right direction but does not reflect the correct procedure that allows continued access under a new employer. Transferring the badge to the new employer is not allowed because badges are specific to the employing organization and must be re-issued to match the employment circumstances. Thus, notifying the airport authority to update badge information is the correct and responsible course of action.
