because when you have a long list of employees, the box pushes down everything else into oblivion
An even neater and better looking thing would be, if the box would just show say the first 5 employee, then with a small button you could extend it to show everyone.
Also I'd change from list to grid view, there are a lot of info which could be also hidden at first, but shown when you click the employee itself. For example, you could just show the employee name on the grid cells (and perhaps the actions you can do with them, ie. performance chart, changing work tier, firing, sending a message etc.), then if you click the name it would extend and show the rest of the info. Sorting the grid could be changed with a button, say sort by employment date, or by production etc. All could be done with flex I think.
