Employee discount

Typically the EPP discount has a special Apple webpage you use to access the EPP discounts. It typically has 'epp' as part of the full URL path.

NOTE: Not all Apple products receive EPP discounts, but I think the Apple Watch does. When I look on my company's EPP link, there is like $9 savings on a GPS+Cellular. Your mileage may vary, as I'm sure your company has a different deal with Apple than my company.

What discount?

Talk to your employer if you think you're supposed to get a discount.
