For example, if one worked as a salesperson for an entry - level position
as a customer service representative in a supermarket chain, the gap would not be scrutinized as much as if the person applied for another sales position.
Since working
as a customer service representative means that you have much responsibility on your shoulders as far as handing over your work is concerned — in this role, you may be handling the cream of the company's customers — it is recommended that you provide sufficient notice in your resignation letter so that you can hand over your work properly.
