Pros
No skill required.... at all. Given the level of skill required is really hard to loose the job... unless you are a dishonest and dumb thief . I had to add the "dumb" because there a re still a lot of dishonest person who still work for the company but sadly are smart enough to not get caught.
Cons
No real training , sort of trial and error ,given the nature of the job, a simple manual would do wonders ( not the generalist staff book ) , store managers do not always follow company standards and procedures especially the one related to safety and fairness ( ex. only one person for heavy delivery cages when the staff manual specify 2 for safety ) . Extra-Eu monopoly in stores create an embarrassing ( and highly offensive ) work environment for whoever know only "english" as second language . Even if your store achieve great profits , you will never have any gratification .
