I was hired to be extra help during the Christmas holidays as a helper . My duties were to merchandise the products we handled and rotate dates and display them in a presentable way on shelves in super markets.
Most of the managers here like to show off their power rather than helping people to get the work done. As a new staff, you can easily be a target for the "higher level" people giving you a very hard time (such as judge you wrongly, bully you, etc.) at the beginning.
