New research from Careerminds UK suggests that replying quickly to after-hours messages from your manager is strongly linked to getting promoted. According to TechRadar, 70.8% of "instant repliers" received a promotion in the last two years, compared with 55.1% of those who waited until the next morning.
The data lands as the UK government has shelved its planned "Right to Switch Off" policy, which would have given workers the right to ignore out-of-hours work messages.
- 70.8% of instant repliers landed a promotion in the past two years.
- 55.1% of next-morning responders landed a promotion.
- 86% of millennials who replied fast were promoted.
- 79% of fast-reply promotions went to men, 60.8% to women.
- The UK government has effectively shelved the Right to Switch Off policy.
What the research actually found
Careerminds lays out the trend clearly. Faster responses correlate with more frequent promotions. Replying immediately to an out-of-hours message sits at a 70.8% promotion rate. Replying within an hour drops to 68.2%. Waiting until the next morning falls to 55.1%.
Generational splits are sharp. 86% of fast-replying millennials got promoted. 47.2% of Gen X staff did. 81.2% of Gen Z did. The effect clusters in the middle of the org chart, not at entry level or the director suite.
A gender split runs through the numbers too. 79% of fast-responding promotions went to men. 60.8% went to women.
Our analysis
This is correlation, not causation. People who are already on the promotion track may feel freer to reply at night. People who aren't may feel safer ignoring the ping. Careerminds isn't claiming that replying at 11pm causes a promotion. It's flagging that the signal exists in the data.
For workers, the practical read is uncomfortable. If you're angling for a promotion, your manager's perception of your responsiveness may weigh in more than you'd hope. That's worth knowing. It isn't worth wrecking your sleep over.
For employers, the message is sharper. If your top people feel compelled to reply at night, you have a culture problem, not a productivity problem. Ireland has had a right-to-disconnect rule since 2021. France has had one since 2017. The UK had been considering similar rules. The current government has shelved them.
The gender split matters too. If men are being rewarded disproportionately for after-hours availability, that's a structural problem dressed up as a merit signal. A promotion system that rewards screen time over shipped work tends to favour whoever can sit at the screen longest.
A worked example: setting team norms around after-hours messages
Say you run a small agency with five employees. You want promotions to reward output, not screen time. Write it down. State explicitly in your team handbook that after-hours messages don't require immediate replies unless marked urgent. Then, when reviewing people for promotion, don't reward availability. Reward shipped work, client wins, and clean handoffs. That breaks the link between promotion and after-hours reachability, and it gives your team permission to disconnect.
What to watch next
Watch whether the new UK Prime Minister, in office as of July 20, 2026, revives the Right to Switch Off. Watch for similar research from other workforce consultancies. Watch whether the gender gap in fast-reply promotions shows up in other datasets. Bottom line: the research is a warning sign, not a recipe. Don't reward availability. Reward output.
