Why you’re still thinking about work after you’ve finished

The laptop is closed. You’re still editing the email in your head.

You take a plate out of the cupboard and find a better way to phrase the second paragraph. Someone asks what you’d like to watch. You say “anything”, because you’re working out whether your reply sounded annoyed.

You logged off on time. The laptop is out of sight. Somehow, the email has joined you for dinner.

Psychological detachment is the research term for leaving work behind mentally during your time off. Unfinished goals can make that harder; so can a heavy workload. And if you’re still answering work messages, logging off hasn’t really marked the end of the day.

Why unfinished work follows you home

An unanswered question can give you plenty to think about. You’ve sent the proposal, but the client hasn’t replied. Tomorrow’s meeting is in the diary, but you still don’t know how to raise the awkward bit.

In a study published in 2016, psychologist Brandon Smit followed 103 employees and more than 1,100 work goals. People found it harder to detach from goals they hadn’t completed, particularly those that mattered to them.

One way to read that finding is that the size of a task may tell you little about how much of your evening it will occupy. Sending an email takes two minutes. Deciding what to say to someone you’ve disappointed can take rather longer.

Unfinished work is one possible explanation, of course. Some evenings you’re replaying an awkward conversation. On others, you’re waiting for a message you know you’ll be expected to answer. “I can’t switch off” can cover rather different situations.

Does making a plan help you switch off?

There is some evidence for it. In Smit’s study, making a plan for where, when and how to deal with unfinished goals helped employees who tended to struggle with detachment.

It’s an appealing idea. “Sort the proposal” leaves a lot undecided. “Tomorrow at my desk, after the team call, I’ll ask Jo for the missing figures” gives you somewhere to begin.

The evidence is less tidy than the advice usually sounds. A later field experiment by Wendelien van Eerde and colleagues, published in 2023, compared goal setting, goal setting with specific action plans, and a group given neither intervention. Across two weeks, neither planning approach improved detachment overall compared with the control group. Among people with a high general tendency to plan, the combined goal-setting and action-planning intervention was associated with poorer detachment.

These were different planning exercises, so the later study wasn’t a direct repeat of the earlier one. Taken together, they suggest that a plan can help some people, but another planning exercise is no guarantee of a quieter evening.

If a brief note makes tomorrow feel manageable, it may earn its place. If you spend twenty minutes moving the same six tasks between days that are already full, the notebook may have done all it can.

What is keeping work in your evening?

Before adding a shutdown routine, look at what you’re carrying home. These three situations offer a useful starting point. They can overlap, and they’re a practical way to think about the problem rather than a psychological classification.

What’s following you home?

The next step is unclear

You keep circling a task because you haven’t decided how to pick it up again.

You’re still on call

You’ve stopped working, but someone may expect a reply tonight.

There’s too much to do

You know what needs doing. There simply isn’t enough time to do it.

If the next step is unclear, leave a note you can actually use. “Ask Jo for the missing figures after the team call” gives tomorrow a starting point. Write it before you finish work, with a realistic time to return to it. There’s no need to turn a reminder into a second planning session.

If you’re waiting for messages, find out what really needs an evening reply. In a five-workday diary study of 116 employees, more work-related smartphone use after hours was associated with poorer detachment. That does not establish which caused which, or mean that your phone is the problem. It does make the expectation to keep working worth examining.

Where you have room to ask, agree what can wait until morning and how an urgent request will reach you. “Do you need this tonight, or is tomorrow fine?” is a more useful question than silently guessing. Of course, some people are explicitly on call. Others have little freedom to negotiate. Switching off notifications won’t settle those arrangements.

If the work won’t fit, the list needs a decision. Smit and Larissa Barber’s research linked heavier daily workloads with poorer detachment, although that relationship varied with self-control and the planning intervention. Planning can still help some people unwind during a busy period. It cannot add hours to tomorrow.

Where possible, make the trade-off explicit: “I can finish the proposal or the report by Friday. Which takes priority?” You may not get the answer you want, particularly if you have little control over deadlines. But it puts the amount of work into the conversation, where it belongs.

You don’t have to finish everything to finish today

There will be days when work comes home with you despite a sensible plan and a closed laptop. You don’t need to spend the evening checking whether you’ve successfully stopped thinking about it.

When the same task keeps returning, try asking:

“What is still unresolved here?”

Sometimes you’ll know what to write down for tomorrow. Sometimes the answer involves another person, a deadline or a decision you can’t make alone.

The proposal may still be unfinished in the morning. Dinner is getting cold now.
