Dad may tell you that he hired one person, not a company. He knows her name, she knows how he takes his coffee, and they have already reached a quiet agreement about which television programs are worth watching. As far as he is concerned, the arrangement is settled.

The paperwork may describe something different. It may allow the agency to send another companion, change the visit time or cancel a visit when no worker is available. Those terms matter because the familiar person is often the reason Dad agreed to have anyone in the house at all.

You are not trying to manage the friendship. You are checking what happens on the ordinary morning when the regular companion is sick, delayed or no longer assigned to him.

Read the missed visit section first

Look for headings such as scheduling, staffing, substitutions, cancellations and service interruptions. Do not stop at language saying the agency will make a reasonable effort to provide care. Ask what that effort looks like.

Write down the answers to these questions:

Who contacts Dad if the companion cannot come? Will they call him, call you or send a message that he may never see? How much notice do they try to give? Does Dad get to accept or decline a substitute? What happens if no substitute is available? Does the visit move to another time, move to another day or disappear?

Also check whether Dad is expected to pay for a visit that the agency cancels. Then read the separate rule for a visit Dad cancels. The two rules may not be the same.

Find out what a substitute is allowed to know

A replacement should not have to learn Dad’s whole household from the bowl where he keeps loose batteries. Ask what instructions the agency keeps for substitute workers and who updates them.

The useful notes are plain ones: which door Dad uses, whether he hears the bell, where the companion should park, what tasks belong in the visit, what Dad prefers to be called and whom to contact if he does not answer.

Keep the list short enough that someone will actually read it. Dad should see it too. This is his house, not a stage set you are preparing behind his back.

If the agreement permits companions to drive Dad, handle keys, buy groceries or use a payment card, read those sections separately. Confirm whether a substitute has the same permission. Do not assume that a task approved for one familiar worker automatically applies to everyone the agency might send.

Ask how Dad can say no without losing the service

Dad may refuse a substitute because he does not want a stranger walking into the kitchen. That is not necessarily stubbornness, although he may deliver the answer with his full supply of stubbornness.

Ask the agency what happens after he declines. Can the visit be rescheduled? Is there a cancellation consequence? Will someone call you if Dad repeatedly turns substitutes away? Could he meet one backup companion while his regular person is still available?

A planned introduction can be easier than having an unfamiliar face appear at the door with a badge and a cheerful announcement that she knows all about him.

Check who may enter the house

Read the key and entry rules. The agreement should make clear whether the agency keeps a key, uses a lockbox or expects Dad to answer the door. Ask who can access any key code and what happens when a worker leaves the agency.

Decide what the companion should do if Dad does not answer. The written steps might include calling him, calling you, contacting a supervisor or requesting a welfare check. Make sure the order fits what Dad wants and that the phone numbers are correct.

If Dad usually naps through the doorbell, say so. A missed knock should not turn into a family drama before anyone tries his telephone.

Compare the agreement with the week Dad actually needs

Put the contract beside Dad’s normal routine. If the companion comes so he can attend lunch, pick up groceries or get to an appointment, a late replacement may not solve the problem.

Ask whether visit times are promised or approximate. Check whether the agreement guarantees particular tasks or merely makes them available. Find out who approves changes and whether verbal changes are later put in writing.

You also want the ending rules. Look for the notice required to pause or stop service, what happens to keys and household notes, and whether unused scheduled visits create any obligation. Keep the signed agreement and later changes together. Dad should know where they are, even if he insists the kitchen drawer is a filing system.

What to do tonight

Find the agreement, the current schedule and the agency’s main telephone number. On one sheet of paper, write the regular companion’s name, the number to call about a missed visit and the person who should be contacted after Dad.

Then ask Dad one question: “If someone different needs to come, what would make that feel all right to you?” His answer may be a telephone introduction, a familiar backup person or permission to decline. Write that preference down and ask the agency whether it can be added to his service notes.

Do not redesign the whole arrangement tonight. Your job is to locate the rule, find the call path and make Dad’s preference visible.

When to ask the doctor

Companion care paperwork cannot answer every question. Contact Dad’s doctor if you notice a meaningful change in how he is eating, drinking, walking, sleeping, speaking or managing familiar tasks. Ask sooner if the companion reports a change that Dad dismisses but cannot explain.

Tell the doctor what you and the companion actually observed, when it happens and what Dad can no longer do as usual. Avoid turning the companion into a medical messenger. Her notes can help you describe the change, but questions about Dad’s health belong with his doctor.

Add this line to the good-week card

If the regular companion cannot come, Dad knows who will call and he can say whether a substitute enters his home.
