48-Hour Excel Roster Automation

I have an existing Excel workbook that I use for staff rostering. At the moment every step is manual, so I want the entire process wrapped into one push-button VBA routine. When I click the button the macro should:

• Allocate each employee to the required shifts
• Detect any conflicts such as overlapping hours or breaches of contracted limits
• Check every assignment against the applicable awards and internal policies, preventing non-compliant rosters from being published

The file is already structured; your job is to build the automation logic, wire it to a clearly labelled button, and return a macro-enabled workbook (.xlsm) that produces the finished roster on demand. Please comment the code so I can maintain it later and include a brief note or screen recording that shows how to run the solution.

Turnaround is critical—I need the completed workbook back within 48 hours of project start. If this sounds feasible for you, let’s get rolling and finish the roster engine in the next two days.
