Edwin Jarvis is the Avenger's butler. In the Silver and Bronze Age, he was sometimes subject to abusive treatment from the Avengers. To be fair, most of the Avengers regretted what they did or where under sometime type of stress or control. Still, you wonder if he could have sued for workplace harassment.
Avengers #16: Jarvis is tied up by Hawkeye and cut free with his arrows. None of the other Avengers seem to object to Jarvis being used as target practice.
Avengers #59: Jarvis is tied up by Yellowjacket.
Avengers #75: Quicksilver manhandles Jarvis.
Giant Size Avengers #1: Wanda tells Jarvis to shut up.
Thor #208: Thor yells at Jarvis.
Giant Size Avengers #3: A possessed Wanda threatens to kill Jarvis.
Avengers #134: A possessed Wanda continues to threaten Jarvis. This time she only wants to fire him.
Marvel Team-Up #41: Wanda, plagued by unknown forces, tells Jarvis to get out.
Iron Man #127: Tony Stark drunkenly tells Jarvis to remember his place as a servant.
Avengers #212: Although teasing, Tigra stalks and jumps out at Jarvis.
Overall, the Scarlet Witch is probably the most abusive.
