While afternoon sleepiness may just seem like a good reason to grab a cup of coffee, serious problems can occur when people are tired on the job. Sleepy people make more mistakes and have poorer judgment. An easy solution to this problem is to introduce napping breaks along with the other breaks companies give their workers. However, there is a serious concern that people will often end up groggier or even more tired after a nap, making such napping breaks ineffective. What is assumed when the claim "napping breaks would reduce the number of sleepy workers" is used to support the claim that companies should establish napping breaks at work? Reducing the number of sleepy workers benefits companies Companies should establish napping breaks at work Taking a nap does not make you even more tired Sleepy workers make more mistakes and have poorer judgment Companies want to make decisions that will benefit themselves
