Staffing standards and labour management at a day service (adult day care) — concurrent duties of the functional training instructor, living consultant and nursing staff

In short: Staffing at a day service (adult day care) turns on placing a living consultant, nursing staff, care staff and a functional training instructor under the designation standard (Standards concerning personnel, facilities and operation of designated in-home service businesses, Ministerial Ordinance No. 37 of 1999, Article 93), then designing shifts that keep meeting those numbers by the "total volume of working hours." The living consultant and nursing staff are counted not by headcount but by hours secured throughout the provision period; care staff must be at least 1 up to 15 users, and above 15 the excess divided by 5 plus 1 (same Article, paragraph 1). At least one of the living consultant or care staff must be full-time (paragraph 6). This article sets out the labour range a Shakai Hoken Roumushi handles — working hours, shifts and full-time-equivalent counting — and separates the interpretation of the standard itself and the designation application to a Gyoseishoshi.

"We meet the standard's numbers, but how do we build shifts that don't fall below when someone is on leave or in training?" and "Can nursing staff double as the functional training instructor?" — these are questions we often hear from labour staff who open and run a day service. This page organises the labour design — working-hours management, full-time equivalents and work rules — on the premise of the day service's staffing. Whether the designation standard is met and whether the application succeeds is the domain of the designating authority (prefecture/municipality) and application practice; this article focuses on the labour thinking.

How are the minimum roles and numbers for a day service decided?

The number of staff for a day service is set in the Standards concerning personnel, facilities and operation of designated in-home service businesses (Ministerial Ordinance No. 37 of 1999), Article 93. The outline is as follows (fine figures and handling change with reform and local operation, so final conformity is confirmed with the designating authority's guidance).

Role	Approach (Article 93, paragraph 1)
Living consultant	Per service day, the total hours worked by a living consultant devoted to the service, divided by the provision-period hours, is 1 or more
Nursing staff	At least 1 devoted to the service per unit (relaxed handling exists for a day service with capacity of 10 or fewer)
Care staff	At least 1 up to 15 users; above 15, the excess divided by 5 plus 1
Functional training instructor	At least 1
Manager	Full-time, devoted to the duty (Article 94; may hold concurrent duties within a range that causes no hindrance)

The point to grasp is that the living consultant and nursing staff are seen not by "headcount" but by "hours secured throughout the provision period." That is exactly why how shifts are built directly governs conformity. The requirement that at least one of the living consultant or care staff be full-time (Article 93, paragraph 6) also ties directly to employment contracts and rosters. What a Shakai Hoken Roumushi handles is not "the number to place" but "how to build the work that meets that number" — shift design, employment contracts, work rules and wage regulations, working-hours management, and social-insurance acquisition and loss. Interpreting the standard and preparing the designation application are a Gyoseishoshi's work, governed by different laws.

Can the living consultant and functional training instructor hold concurrent duties?

Whether concurrent duties are allowed is decided in detail by the standard and the local authority's interpretive notices; in labour, we manage "how many hours of one person's work are allocated to which duty" on that premise. The general thinking is as follows (specific eligibility is confirmed with the designating authority).

• The functional training instructor is normally allowed to hold concurrent duties at the establishment. But only qualified people can be the functional training instructor — physical therapist, occupational therapist, speech-language-hearing therapist, nursing staff, judo therapist, anma-massage-shiatsu practitioner, acupuncturist or moxibustion practitioner
• The living consultant and nursing staff may also hold concurrent duties in certain conditions, but that time falls outside "time devoted to the day service," so care is needed in the throughout-provision-period calculation
• When holding concurrent duties, note that the total volume of one person's working hours does not change. Concurrent duties juggle numbers; they do not add working hours. Overtime, late-night and holiday premiums (Labor Standards Act, Article 37) are calculated on the aggregated actual hours across duties

For concurrent-duty design, it is safer to record on the roster which time is "living consultant" and which is "care staff," so it can be verified later.

How do you manage the nursing staff's "securing throughout the provision period"?

A day service's nursing staff must be secured, per unit, devoted to the service; you build shifts so they can be placed throughout the provision period from opening to closing. Where labour trips up:

Issue	Labour handling
Nursing staff absent partway through the provision period	Risk of falling below standard. Design in advance in the shift how to fill break/step-out time
Paid leave/absence with a single nursing staff	A substitute is needed. A one-person-dependent structure has a high risk of falling below standard
Part-time nursing staff working hours	Manage by actual hours and state prescribed hours in the contract and notice of working conditions (Article 15)
Granting breaks	45 minutes over 6 hours, 1 hour or more over 8 hours (Article 34). If there is a duty to respond during a break, it can be hand-waiting time and thus working time

A structure with only one nursing staff collapses when that person is off. A shift that builds in time lost to paid leave (Article 39; the employer's duty to designate 5 days) and training is the practice that prevents falling below standard. Work rules must be prepared and filed at establishments with 10 or more workers at all times (Article 89). See from how many workers must you prepare and file work rules.

How do you calculate full-time equivalents in shifts?

The full-time-equivalent number is the total scheduled working hours of the establishment's staff divided by the hours a full-time staff member should work. The required number of care staff is also met by this thinking, as a "total volume of working hours."

Item	Content
Formula	FTE = (total scheduled hours of all staff) ÷ (hours a full-time worker should work)
Full-time hours	Prescribed hours set in work rules (e.g. 40/week). The ceiling under Article 32 is 8/day, 40/week
Part-time staff	Counted into the total by their actual hours
Fractions/margin	Build with a margin so as not to fall below even when hours drop for leave, absence or training

Note that the full-time equivalent is seen by the total volume of working hours, not by headcount. One full-time worker at 40 hours and two part-timers at 20 hours each are the same "1." Because a day service's provision period is fixed to daytime, a design that secures the needed numbers on service days while staying within 40 hours a week — using a variable working-hours system and shift ingenuity — is realistic. For choosing between monthly-unit (Article 32-2) or yearly-unit (Article 32-4) variable systems, see how do you choose between a variable working-hours system and flextime.

How does falling below the staffing standard affect fees, and what do you prepare in labour?

A continued state of falling below the standard can lead to a reduction in care fees or matters affecting the designation. Calculating and billing fees is the domain of the operator, the Federation of National Health Insurance Organizations and the local authority, but work management to avoid falling below the standard is a central labour task. In labour, you prepare:

• Record work results objectively. Keep start/end times, breaks and the duty distinction (when concurrent) on rosters and time cards, so full-time-equivalent conformity can be verified later
• Overtime and holiday work within the 36 Agreement (Article 36). Continuously filling thin days with overtime risks exceeding the ceilings (in principle 45 hours/month, 360 hours/year)
• The extinctive prescription of a wage claim is 3 years for the time being (Article 115 and Supplementary Provisions). An error in premium calculation risks three years' worth being claimed together, so calculate premiums accurately
• Align the wage requirement of the treatment-improvement addition with the work rules. The wage improvement under the addition is reflected in work rules and wage regulations. See how do you reflect the care treatment-improvement addition in wage regulations

Whether an individual reduction applies, and calculating and billing care benefits, are the domain of the designating authority and the Federation, outside this article's scope. We do not make specific judgments on care-fee billing.

Whom should you separate the staffing standard and the labour work to?

In opening and running a day service, who decides divides by role. Separating the roles and entrusting each to its professional is safer.

FAQ

Q. Can nursing staff double as the functional training instructor?
A. Those who can be the functional training instructor are qualified people — physical therapist, occupational therapist, speech-language-hearing therapist, nursing staff, judo therapist, anma-massage-shiatsu practitioner, acupuncturist or moxibustion practitioner — and nursing staff holding this qualification can generally double as the functional training instructor. But even with concurrent duties, the total volume of one person's working hours does not change, and premiums are calculated on the aggregated actual hours. Specific eligibility is confirmed with the designating authority.

Q. Must the living consultant be full-time?
A. The living consultant itself need not be full-time, but at least one of the living consultant or care staff must be full-time (Ministerial Ordinance No. 37 of 1999, Article 93, paragraph 6). Which to make full-time is a matter of employment-contract and shift design, within a Shakai Hoken Roumushi's range.

Q. Can the full-time equivalent be met just by headcount?
A. No. The full-time equivalent is seen by the total volume of working hours — the total scheduled hours of all staff divided by the hours a full-time worker should work. When total hours fall due to paid leave, absence or training, there is a risk of falling below the standard, so a shift design with a margin is a premise.

Q. Can conformity with the staffing standard and the labour work be entrusted to the same person?
A. Because the governing laws differ, they are considered separately. Interpreting the staffing standard and preparing the designation application are for a Gyoseishoshi; shift design, work rules, working-hours management and social insurance are for a Shakai Hoken Roumushi. At Yotsuba, 四葉行政書士事務所 and 四葉社会保険労務士事務所 are independent business entities, dividing the work under separate contracts.
