The main downside at working for Aveda is pretty much that I have spent a lot of my paycheck on the products! The upside to that is that employees are offered a discount.
The only downside I truly see is that newcomers to Aveda, in my eyes, have not seen the company before Estee Lauder took over and might not appreciate the company in it's "previous life", but on the upside, newcomers to Aveda can bring a fresh perspective, since good business is all about change and bringing in a new generation.
I'm still hoping Aveda will continue with adding ingredients that are not toxic, that they keep the integrity of quality Aveda is famous for.
