Is an unpaid trial shift legal in the UK?
No law names the trial shift. But government guidance draws a line, and a full unpaid day is usually on the wrong side of it.
- Guidance says an unpaid trial of a few hours can be reasonable; one lasting more than a day is likely to need paying “other than in very exceptional circumstances”.
- Acas suggests a trial of, for example, two hours or one shift, and says unpaid trials should usually last no more than a day.
- Calling it a “test” or a “trial” doesn’t change your rights if you’re doing real work.
