vWork also has the ability to assign multiple workers to a job. In this scenario, there is a master worker responsible for all the custom fields and their are subworkers that get read only copies of the job and the ability to record their start and finish times.

Whilst this is not fully supported by the API at this stage, you can create a job with this functionality enabled and add the master worker. Dispatchers then have the ability to add sub workers as needed.

To use this functionality, ensure that it has been enabled on your account and then tick the box for "Allow Additional Workers" on the template itself.

You can then simply create a job using that template name.
