One of Star Trek icon William Shatner’s former employees is suing the actor over allegations he forced him to quit his job.

Oscar Alfaro has filed suit in Los Angeles claiming he was "harassed and berated" by the star after he refused to sign a waiver following an accident on Shatner's estate.

Alfaro claims he and his wife worked for the actor for 20 years, but they were both forced to resign when Shatner turned on them after he refused to sign legal paperwork excusing the star from any financial responsibility connected to his employee's injuries.

Alfaro claims he and his wife suffered humiliation, embarrassment and mental anguish, and they're suing for loss of earnings and other unspecified damages, reports TMZ.com.
