There are moments in time when caregivers are needed. If your character is elderly, injured, recovering from surgery, mentally disabled, or a pregnant woman on bedrest, someone may be hired to help them out. Caregivers can be round-the-clock and live-in helpers or they might come during certain hours when family members aren't available. They might be hired for a limited period of time or in perpetuity. They may be a professional caregiver or a neighbor or friend of the family who is hired to do the job. Regardless of the details, this relationship is based implicitly on trust, with a vulnerable party depending on someone to meet their most basic needs.

Below are a wide range of dynamics that may accompany this relationship. Use the ideas that suit your story and work best for your characters to bring about and/or resolve the necessary conflict.

A more personal relationship where both parties express an interest in each other's lives
A caregiver who sees and does whatever needs doing, even if doing so takes them outside their scope of duties
A purely professional relationship, with the caregiver clocking in, doing their duties, and clocking out as needed
A client who treats the caregiver as a servant or lackey
A caregiver who meets their client's needs while secretly taking advantage of them behind the scenes
An apathetic caregiver who's only in the job for the paycheck
A client struggling with a lack of control or dissatisfaction with their circumstances taking their frustrations out on the caregiver
An abusive relationship, one way or the other
A healthy relationship that is undermined by interfering, selfish, or drama-seeking family members

A client's condition worsening
Money running out, making it difficult or impossible for the client to pay for a caregiver
A situation that steals the caregiver's time, such as them moving farther from the client, having to take on a second job, or starting a romantic relationship
A personal friend offering to do the caregiver's job for less money
The caregiver becoming injured or sick and needing care themselves
The caregiver becoming attracted to a family member
