Generally, inside sales teams have a reputation for high turnover. Inside sales reps can have a short shelf life before they get enough experience to be considered for a sales role with more accountability or perhaps a client facing role. With the internet being available everywhere and at your fingertips through smart phones, it still surprises me when an inside sales representative resigns without a resignation letter or 2 weeks notice. It’s not difficult to Google resignation letter templates. A resignation letter can be as basic as 2 lines. I am resigning. My last day is X. It is respectful to give 2 weeks notice but not always necessary. The moral of the story is, don’t forget your manners when you decide to resign from your current position.
