To ensure that the worker can submit the timesheet you will need to start the assignment on the date the work is expected to be carried out. You must end the assignment on the following day.  


Please ensure you do not put the end and start date as the same or the worker will be unable to view the timesheet. 

When creating assignments best practice is for the assignment to start on a Monday and end on Sunday, even when the assignment is only for a few hours / days during that duration.  This will avoid overlapping of assignment and make it clearer for you to view as a Hiring Manager.
