Occupation Switch Board Operator, Secretary


Lois Sadler was a switch board operator and eventually a secretary at Sterling Cooper Advertising Agency. She was known for acting inappropriately, incompetently, and unprofessionally, usually in a humorous fashion.

As switchboard operator, she was seen listening in on a phone conversation between Salvatore Romano and his mother while they were speaking Italian. She had a crush on Sal and asked the other secretaries about him. Later, she invented a pretext to run into Sal and ask him out, and she says "ciao, ciao" to him, in imitation of his phone call she eavesdropped on. ("The Hobo Code")

After Peggy became a copywriter, Lois became Don Draper's secretary. She was reprimanded by Peggy for making an unprofessional remark about Don's activities when Peggy asked where Don was (Don has a habit of disappearing and being incommunicado for hours at a time, so Lois implies to Peggy that Don is not where he claims to be). Later, Joan Holloway chastised her both for crying at work after Peggy's reprimand and for complaining to others about Peggy. ("For Those Who Think Young") She was eventually fired as a secretary (but remained a switchboard operator) by Don for incompetence, or, as he put it, for not "managing people's expectations". ("The Benefactor") This was the result of her not covering for Don, nor keeping him informed in an appropriate manner about client activities. Specifically, the owners of Utz Chips (Kurt and Edith Schilling) stopped by the office with Ken Cosgrove, and then Ken took them to the set of the commercial being filmed by comedian Jimmy Barrett, who then proceeded to humiliate Edith Schilling by ridiculing her weight. Had Don (who was out watching a movie but said he was at the printer's) been properly informed by Lois, he would have prevented the Schillings from being with Jimmy Barrett or made sure Jimmy was properly informed of who the Schillings were.

Later, when she was questioned by Ken Cosgrove, Paul Kinsey, Sal, and Harry Crane about certain unusual activities happening at Sterling Cooper, she very unprofessionally informed them of the merger with Puttnam, Powell, and Lowe, allowing Don the opportunity to plan countermeasures against them. She also made them promise to take her off of the switchboard if any of them managed to keep their jobs. ("Meditations in an Emergency")

After the merger, she became Paul's secretary. She was enlisted by Paul, Harry, and Ken to prank call Peggy in response to Peggy's want ad for a roommate. ("The Arrangements")

Later, while celebrating at Joan's farewell party, she took a turn driving the John Deere mower around the office that Ken brought in after landing an account with them. She had trouble controlling the steering and ended up running over the foot of Guy MacKendrick, a British man who was poised to replace Lane Pryce as head of Sterling Cooper. ("Guy Walks Into an Advertising Agency"). MacKendrick lost his foot, and, it is implied, his job. Miraculously, she continued to work for the company after this, as she was seen rousing a drunken Paul. ("The Color Blue")
