We pride ourselves on being a "family business"
and regret whenever we have to let an individual go
because of poor performance.
Unfortunately, unless several flaws in your performance
are rectified immediately, we will have to terminate
your employment with us. Customers have reported dissatisfaction
with your customer service and have cited your reluctance
to assist them.
I'm sure you will take steps to resolve these issues
and that all of this can be worked out without any further
complaints occurring, and with no further reminder required.
