Pros
You do get benefits if you're part time at 20 hours a week. If you have no career aspirations are content with occasional lateral moves within the organization, I’d recommend it as a nice job if you like working in customer service. It’s a relatively safe work environment. Job security is great.
Cons
Little to no room for advancement or growth despite any extra effort you put into your work or into expanding your knowledge base about the organization and the services it provides. Even though current managers & the Director were librarians who were able to work their way up through the ranks, those same women now seem to have instituted a standard of not promoting current employees if they can at all help it. Outside candidates are usually, if not always, chosen for the higher-paying jobs, indicating a sentiment that current employees simply aren't qualified to those same openings, despite their Sno-Isle experience. On their employment home page Sno-Isle claims to provide "...continuing opportunities for training and development, so you can explore a career that will be vital and interesting for years to come." This doesn’t appear true as I can say that I’ve rarely, if ever, seen it practiced: see above comment. Job security is great: no matter how poorly someone may perform their job, they won't be fired; the poor performance will just be ignored, or they’ll be moved to another position.
