Managers are usually pretty persistent about their employees selling attachments (ms office, eset anti-virus and service plans). This can be stressful if your not getting many of these attachments on your sales and If your working in a higher department maybe even a demotion, but this would be pretty hard as even some of the worst sales guys in my department would still do ok for themselves. This will vary depending on the manager, my original manager was pretty chill and realistic with meeting quotas for attachments whereas the new manager was very pushy and wouldn't shut up about selling attachments. Pray your manager isn't the type to give you the impression that this job is the most important moment in your life and everything you do is crucial to your sucess.
