{ name: 'Rich Holcomb', id: 'E01234', salary: 49500, dept: 'D050' },
{ name: 'David Motsinger', id: 'E27002', salary: 19250, dept: 'D050' },
{ name: 'Tim Sampair', id: 'E03033', salary: 27000, dept: 'D101' },
{ name: 'Kim Arlich', id: 'E10001', salary: 57000, dept: 'D050' },
{ name: 'Timothy Grove', id: 'E16398', salary: 29900, dept: 'D101' }

{ name: 'Rich Holcomb', id: 'E01234', salary: 49500, dept: 'D050' } ],
[ { name: 'Timothy Grove', id: 'E16398', salary: 29900, dept: 'D101' },
{ name: 'Claire Buckman', id: 'E39876', salary: 27800, dept: 'D101' } ] ]
```
