If you work in the customer service field, you start work at 7 a.m. and finish at 4 p.m., if you work in healthcare you start at 8 and finish at 5, if you work in IT you start at 9 and finish at 6, etc. The system is imposed or/and incentivized by the government, so the majority of the residents participate.
The background: Staggered work hours (SWH) is a transportation demand management method used to reduce traffic. It is usually applied to individual companies to divide the workers within the same company into groups and assign different working hours to each group. I propose implementing this on a municipal level and instead of grouping the workers within individual companies, forming large groups according to the job sector people work in.
To include as many residents in the project as possible.
To make the system more concrete and more organized, therefore more effective. Forming groups within individual companies is a loose approach, some companies participate, some don't, also, the staggered groups within the company are unstable - workers might move back and forth upon demand.
To make people get used to this over time, accept the situation as "the way things are" and adapt accordingly. Choosing a certain job sector means choosing certain working hours. Changing the sector means different working hours.
To let all the employees in the same company/department work at the same time.
How it works (the details):
The system would target general "office hours", in other words, the jobs that are not time-sensitive and can account for flexibility. Even for different job sectors, general office hours are usually similar. For example, if you work as a barista in a cafe, the start of your work depends on the opening time of that establishment, so you can hardly participate in the project, but if you work as a customer line support specialist (still customer service field), you can.
For a start it would be enough to take a few major job sectors, containing the majority of the employees or group different job sectors together to form larger clusters, for example - customer service, marketing, and accounting can form one cluster, IT, public relations and education another, etc. Jobs in different clusters have different start and end hours.
The same system can potentially be applied to educational institutions - universities, colleges, etc., depending on the educational field a certain institution belongs to - natural science, humanities, politics, etc.
