Pros
You get paid to talk about playing games and building models with people that are, generally speaking, also excited about playing games and building models. The benefits are pretty decent, pay is adequate for what it is.
Cons
It's retail, but more so. That is to say, retail always involves horrible people (the public) along with some very nice people, but Games Workshop attracts lots of people with limited social skills that have often put in a significant monetary investment and who now feel alienated by the recent insane push to spend more even as you get less back for your dollar (or by obscure quirks in the game that are no one's fault). I'm not sure what the deal is with the pricing plan, but it seems as though management is just experimenting to see how much they can charge. All well and good, but they act confused when nobody buys the brand new $150 box and pass blame off on the Hobby Center Operators instead of learning that yes, there is a point people will stop buying. If you plan to work here as a career, seriously re-examine your life. Not because working here is not honorable, but because there isn't really any room for advancement unless you make the right friends upstairs, and the salary is certainly not adequate for anything except the most basic lifestyle. Also, job security is laughable. The company is reorganized every 6 months (or so it seems), with anybody above HCO having to reapply for their same job/new title. HCOs are fired early and often, and there is basically no help for any HCO that is struggling other than the knowledge that if you don't start doing something right soon you'll be looking for a new job.
