1. The manager should not discuss the employee's status in front of others. That is a personnel matter and it is not our business. It may be hostile.
2. Even if this is an ongoing issue with the given employee, it is not our business.
3. My personal peeve: as my real self, I have had enough of up-sell. I do not want suggestions for more of stuff I do not need. This sales patter needlessly lengthens the duration of transactions, and sometimes I want to get my purchases quickly and move along quickly. If I do this type of shop, someone who does not up-sell or suggest what I do not need and delights my real self could have trouble with their employer for not meeting a corporate goal, which is to irritate my real self, I mean, try to sell me stuff I do not need and lengthen the duration of my transaction. Even if I do not do this type of shop, employees who do not up-sell may be dinged for doing what delights me-as-real-customer-who-does-not-like-up-sell.
Nature does not hurry, yet everything is accomplished. - Lao-Tzu
