So if an individual worked 08:00 - 16:00, you would only count 09:00-16:00?
When dealing with day-of-week calculations, it's important to take account of the current DATEFIRST settings. This query will always correctly exclude weekend days, using @@DATEFIRST to account for any possible setting for the first day of the week.
SELECT *
FROM your_table
WHERE ((DATEPART(dw, date_created) + @@DATEFIRST) % 7) NOT IN (0, 1)
You can get the difference between the two dates to whatever resolution you want (in your example, minutes):
DATEDIFF(minute, @start_date, @end_date)
