General question on a multi-select control (best practice)

I wrote a schedule app -- in asp.net 3.5 -- used where I work to do all the scheduling, and it actually turned out quiet nice. The issue is, you can only schedule one employee at the time.
Each job is one row in a database and equals one employee.
We have a lot of jobs that involve multiple employees, so it would be much easier to create one entry that schedules 3 employees for the same job.
I've looked at a lot of multi-select dropdowns and combo boxes. Here is what I would like some advice on.
If multi-select selects employee numbers 2202, 2403, and 3610...how is the best way to get that into the database?
I'm thinking 2202, 2403, and 3610 get put into an array, and use a loop to add each entry into the database. The database stays the same, and when this gets posted, there are three new entries in the database, one for each of the employees.
Am I thinking right or ...
