Retail is not for everyone
I highly recommend making sure you speak to others about working in the retail environment before taking on this position. The hours are very long (can often amount to 10-11 hours on your feet, in the shop per day, including every alternate weekend) and there is a lot of tedious work to do, such as constantly counting hundreds of small items of stock, checking expiry dates on each product, cleaning the shop etc. It is also quite difficult to take leave for important events and you will be working throughout the holiday season, including Christmas and new years.
It is difficult to balance work life and personal life in this position, as you often will finish after 7pm and work full-days on weekends. You are physically exhausted at the end of each shift, since you're on your feet and constantly walking, cleaning, bending, lifting etc. Most of my colleagues were physically and mentally fatigued when I was working there. The employee turn-over is also quite high - many employees leave within a month or two of working there due to burnout.
The training was very interesting and thorough - we got treated to amazing food and got lots of free samples of health products.
The amount of health-consulting done is minimal compared to the amount of shop-cleaning and stock-counting done. Consider this a stepping stone position and not ideal for anyone with strong interpersonal commitments.
