The worksheet 'job1' contains 6 workers named 'worker1'...'worker6';
The worksheet 'job2' contains 2 workers named 'worker1','worker3';
The worksheet 'job3' contains 9 workers named 'worker3', 'worker2', 'worker4',....;
I want to copy those names from the worksheets to worksheet 'sheet1'.

The number of workers in each worksheet maybe different. How to automate it?

What formula should be put in 'sheet1' to automate this work?
