The link between work and time has been evolving as a major element of social progress over centuries. In what younger generations seem to take for granted, <40 hours week, paid time off-work. 4-5 days per week to name only the major ones, has been the result of huge struggles and hustles driven by employees and their trade unions to achieve such milestones. The current debate to get employees back into offices and/or to work longer hours again, is also in the end a debate about work and time. The advantage of working from home consists among other factors in saving a lot of valuable time and stress from commute to work. This unaccounted time to go to work has become a major health hazard even in an apparently comfortable company subsidized car or any other means of transportation. The traffic jams of so-called rush hours, when in fact everybody is slowed down, are a serious health hazard usually ignored by employers. However, these hours are a major part of the work-life-time balance of employees. In many negotiations and collective bargaining about working time this is the big elephant in the room rarely addressed.
