Mackenzie Phillips Reflects on Her Journey with ‘One Day at a Time’

Mackenzie Phillips, known for her role on One Day at a Time, recently shared insights into her departure from the series. At the Fanboy Expo Knoxville in Tennessee, Phillips discussed the “morals clause” in her contract that played a part in her exit.

Behind the Scenes Challenges

One Day at a Time made Phillips popular alongside co-stars Bonnie Franklin and Valerie Bertinelli. However, Phillips struggled with addiction, leading to specific provisions in her contract. According to Phillips, producers could subject her to a urinalysis if they suspected she was under the influence.

Phillips recalled a particularly significant moment during a lunch break on set. She was asleep on the couch when Patricia Fass Palmer, a co-executive producer, woke her to inform her of the need for a drug test. Initially, Phillips wanted more time, but Palmer insisted they conduct the test immediately, leading to Phillips’ departure from the show.

Life After One Day at a Time

Phillips’s character was written off after her firing, but she returned for a guest arc before leaving permanently in 1983. In recent interviews, she has candidly discussed her battle with addiction. During lunch breaks on set, she and Valerie Bertinelli would drive to Phillips’ house to drink wine and snort cocaine.

Resilience and Recovery

Faith and resilience have helped Phillips navigate her personal struggles. She emphasizes the importance of her history, which she believes has driven her empowerment. Despite the difficulties she faced, Phillips views them as contributing factors to her current strength.

She continues to speak openly about overcoming addiction, inspired by her belief in resilience and the supportive love of her family. Phillips has also leveraged her experiences to assist those battling addiction, working in the field as a counselor.
