unforewarned

Caught off guard

Unforewarned means not given advance warning or notice.

Someone unforewarned walks into a situation without having been alerted to what awaits them: Unforewarned of the merger, employees arrived to find their jobs eliminated.

The word emphasizes the absence of preparation that a warning would have provided.
