According to Claude AI.....
In Ireland, unpaid trial shifts are illegal. Here's the key point:
Under the Organisation of Working Time Act 1997 and the National Minimum Wage Act 2000, any time a person performs work for an employer — including a trial shift — they are entitled to be paid at least the national minimum wage.
A trial shift is considered work, not training or observation. If someone is serving customers, preparing food, or doing any productive task, they must be paid regardless of whether it's framed as a "trial."
What's allowed:
A short skills demonstration (e.g., 15–30 minutes of observed food prep or a practical test) that's more of an interview assessment may sit in a grey area, but once it extends to a full or substantial shift, payment is legally required.
Unpaid job shadowing where the person is purely observing and doing no actual work is generally considered acceptable.
If an employer doesn't pay:
The worker can make a complaint to the Workplace Relations Commission (WRC) at workplacerelations.ie
The employer risks a WRC award ordering back-pay plus potential penalties
This is a well-known issue in the Irish hospitality sector, and the WRC has ruled against employers in such cases. So to answer directly: no, it's not legal to ask someone to do a productive trial shift without paying them.
