System of wristbands to monitor employee stress, and provide rest
Wear specialised devices that measure stress
People at workplaces should wear a wristband that monitors their heart rate and other factors. This could measure how tired people are, and warn them to finish work at critical times. This wristband can function in conjunction with a workplace environment which allows people to produce as much work as they can manage, rather than as much work as deadline or project dictates.
