When the Working Day Has No Natural End

Some work has an ending built into it. The shop locks its doors at five. The last delivery is signed for. The till is counted, the float is set aside, the lights go off. Whatever is left over belongs to tomorrow, and everyone knows it.

A lot of modern work has no such moment. Orders arrive through a website and WhatsApp at any hour. Customer queries sit in an inbox that is never empty. A project tracker always has something overdue. There is no closing time for a queue, so the person working it has to decide, every single day, when to stop. For many people that decision is made not by the clock but by exhaustion, guilt or a family member asking whether they are coming to supper.

This piece looks at that missing ending: what it costs, why it happens, and how a business can design one back in.

A boundary the law sets, and one it cannot

South Africa's Basic Conditions of Employment Act limits ordinary hours of work to 45 hours in any week, and to nine hours a day for someone working five days or fewer a week. It also requires a daily rest period of at least twelve consecutive hours between ending and recommencing work. Those limits are real protections for employees, but they define a maximum, not an ending. They do not tell anyone at what point today's queue is finished.

The country also has no specific right-to-disconnect law. A 2024 commentary from the South African law firm CK Law notes that such legislation exists in countries such as France, Spain, Ireland and Australia but not here, and that South African employers have so far been left to manage after-hours availability themselves. Owners and many senior staff are in an even weaker position, because their working time is shaped by the business rather than by any contract.

What the evidence suggests

Microsoft's analysis of what it calls the infinite workday describes a working day that, for many people in its data, stretches well into the evening. It reports that the average worker receives more than 50 messages outside core business hours, that meetings after 8 pm rose 16% year on year, and that around 40% of people online at 6 am are reviewing email for the day's priorities. These figures come from users of Microsoft's software around the world, not from South African small businesses, and they describe activity, not wellbeing. They do show that the edges of the working day have become blurred for a large number of people.

What they cannot show is why. The argument here, which is a reasoned hypothesis rather than a measured result, is that one important reason is structural: much of today's work is organised as continuous queues, and continuous queues have no natural end.

How a queue erases the end of the day

Consider an illustrative case: a Bloemfontein business selling agricultural spares to farmers, with eleven staff. It used to take orders by phone during office hours. Now it also takes them by WhatsApp and through a simple online store. Farmers send messages at dawn and late in the evening, because that is when they have time. The two people who handle orders feel, reasonably, that a farmer with a broken pump should not wait.

Several features of the setup mean that the day never closes:

No cut-off time. Nothing tells customers or staff that orders received after a certain hour are handled the next morning. Every message is implicitly urgent.
No shared view of what is left. The WhatsApp queue lives on one person's phone. Nobody else can see what is outstanding, so leaving it feels like abandoning it.
No handover. There is no end-of-day note that says "these three are waiting, they will be done first thing". Unfinished work stays with the person who started it.
No distinction between urgent and merely recent. A breakdown and a routine restock arrive in the same channel, looking the same.

Mellorca has written about the weekly version of this, where unfinished work spills across the weekend boundary, in Friday evening should start on Friday evening. The daily version is quieter but more frequent. It is less about a big piece of work that did not finish and more about a stream that is never allowed to pause.

The human tax: time, autonomy and energy

The time cost is the extra hour, or the scattered half-hours, given to the queue after the official day is over. The autonomy cost is that the person is no longer the one deciding when they stop. The queue decides, or the customer does. The energy cost builds over weeks: a day without a clear end is followed by a morning that starts with whatever arrived overnight.

These costs are not felt equally. Some people like answering a message at 9 pm because it suits the shape of their lives. Some feel genuine satisfaction in being the person a farmer can rely on. The concern is not that late work happens, but that nobody has chosen it. The ending has disappeared by default rather than by decision.

What could change

An ending can be designed. For the illustrative spares business, that might mean:

Publish a cut-off. Orders received after, say, 4 pm are dispatched the next working day. Telling customers this in an automatic reply sets expectations without anyone having to say it each time.
Give genuine emergencies a separate route. A breakdown line, staffed on a rota if needed, means urgent cases are not lost in the general queue, and the general queue can wait.
Move the queue off a personal phone. A shared inbox or business messaging tool lets colleagues see what is outstanding, so stopping does not mean hiding work from everyone else.
Close the day deliberately. A short end-of-day routine, listing what is waiting and who takes it first tomorrow, turns "unfinished" into "scheduled". It is the digital equivalent of cashing up.
Look at what fills the queue. If many messages are customers asking whether an order has shipped, a dispatch notification may remove them altogether.

Some of these are technology changes, but most are decisions about how the work is organised. Mellorca's broader view of this is in when work sits waiting more than it moves and the hidden cost of operational friction.

Trade-offs

Some customers will go elsewhere. A competitor who answers at 9 pm may win some orders. A business has to decide whether that is a price worth paying, or whether a rota for late orders is fairer than leaving it to whoever happens to be holding the phone.
Cut-offs can feel rigid. Staff who prefer to work flexibly may resent a fixed close. The ending should be a default, not a ban.
A shared queue is visible. Moving work off a personal phone gives colleagues visibility, which can feel like oversight.
The rota still costs someone. An emergency line shifts the burden to the person on duty. It is better than everyone being on duty, but it is not free.

Why it matters

The operational case is that work handled in a defined window, with a clear handover, tends to be handled more consistently. The human case is about agency. When a working day has an end, the person gets to decide what happens after it: rest, family, study, a second job, sport, or nothing at all. When it does not, that choice is quietly made for them by a queue.

That is the dividend: time that is clearly one's own again, and the autonomy to choose whether to work late rather than discovering, at 10 pm, that one has.
