Set up your shifts
Define your usual shifts - early, late, night - with start and end times, so adding them is one click.
Staff against days
A grid with staff down the side and days across the top shows the whole week at once, and gaps stand out.
Check for clashes
Watch for anyone booked twice, and for overnight shifts that run into the next day's early start.
Hours against target
Compare each person's weekly hours with their contract or target, so nobody is over- or under-scheduled.
Copy the week forward
Start next week from this week, then change what's different.
