Pros
Like stated before huge company with job security. Sherwin is eating up smaller paint companies and spreading its wings. Work within a small crew at the store which created a close knit group. You meet people from all walks of life and create relationships with customers. You get sales experience that would come in handy anywhere else.
Cons
I've been working for two years at sherwin and have never felt like my job was at risk. I love working at Sherwin. However, I've been part-time for 2 years. I've applied from within to try and grab the next step of the ladder for a full-time or assistant manager position with no luck. I'm professional, knowledgeable and competent in my position. I feel like I stand out but Upper management tends to already have a selected person in mind to fill positions posted. The job can get a little repetitive/boring if you work in a smaller store.
