A polite way of telling someone you have to let them go

[costat]

What is a polite way of telling a long-term and loyal employee that you have to let them go? I know the word απολύω, but I'm wondering if there is something a little softer. This is a very difficult task I have to face and I want to find the nicest way of doing it possible.

The full sentence would be: "Due to circumstances beyond my control, I am, unfortunately, going to have to let you go."

Thank you.
