Perfectly legal if you say you'll pay a worker say 50p for each unit they produce, knowing full well that the maximum number of units it's possible to produce is 4 per hour. I believe lots of Eastern European workers got caught out with this scan for cleaning hotel rooms in central London. No doubt it's all the fault of lazy British workers though![]()
Not legal at all - if you offer piece pay the worker still needs to earn minimum wage + holiday pay based on time worked. Employers have to top up wages of underperforming workers.
