Pros
Job security, large brand which is constantly growing and expanding. Opportunities to transfer and work in different countries in Europe if you speak the language. Great 25% staff discount. Commission with each pay cheuqe depending on the performance of the store - 1% for sales staff and 2% for cashiers. Relatively flat structure so most staff are in the same boat with regards to responsibility, expectations, etc which creates a sense of togetherness. Most stores have a dedicated stock room team. Handheld devices which (in theory) allow for easy stock check. Consistent managerial style. Stores renovated every few years. Great location.
Kontras
Can be incredibly busy at times with very little change in staffing levels to reflect this. Stores seem to be constantly understaffed which can make completing even the simplest of tasks seem overwhelming. Unwillingness to open another till/cash desk at peak times puts cashiers under massive pressure and results in huge queues and unhappy customers to deal with. Equipment has a tendency to break or die when you most need it. Complicated pay structure (although this is common across the industry). Working at Zara involves a remarkable amount of cleaning - once the store has closed you are expected to stay behind for around one hour to tidy the store. No real scope for promotion but in reality only a select few will want to progress their career at Zara.
