Pros
It's a good starting point, but it's just that: a starting point. You'll learn the base line of the fast food industry and customer service, which you can carry with you anywhere. If you work corporate and have the proper connections, you can work more than one store to get your hours, which is a huge plus if you've got the transportation and both GMs are cool with it and you. Better food quality than most competitors, half off your meal if you're crew and free if you're management, good and flexible hours -- at the stores I worked, there was none of that -30 hour requirement for crew members to avoid the Obamacare laws and that is a huge point of respect I have for this company that I hope is companywide. That said, healthcare offered if you work the appropriate hours and you may find yourself working with some pretty cool people you'll be glad to have met when you leave.
Cons
The pay leaves more than a little to be desired. Crew starts out at $7.25 and have the ability to earn $.25 every six months. Keyword: ability. I never saw any crew member get that $.25 raise, even those who were trained and capable of functioning flawlessly in all positions, who came to work on time, stayed when asked, came in on their off days, went above and beyond, gave excellent customer service, took initiative, and were constantly attempting to assist or asking how they could. There's allegedly a cap for crew (manager's starting at $8.50, I think?) and it's too low for anyone who does wind up working food service steadily (which does happen and is nothing to be ashamed of) to survive on, which means limited growth potential unless you continue climbing the ladder and the raise you get for going to shift isn't too much more. Tl;dr, you're undervalued as per the fast food industry in terms of pay and if they could legally pay you less, they would, so don't get attached, always keep your standards high, and don't be afraid to hold your company to them. You aren't allowed overtime and they'll scream bloody murder over that extra few dollars you make if you get it even if several people didn't come in that week and they have the funds and can afford that labor, which is ridiculous. If you're injured on the job, they'll take care of your medical bills, but be prepared to jump if you don't want to lose money despite being injured if it isn't a worker's comp case. Carpeted floors in a lot of the older stores. Older stores come with their on unique set of problems. Grease! You're going to be coated in it every time you work and that plus the sweat from the headsets are going to make your ears, hair, and face a major care point. If you're a lady, grease buckets may be a challenge as they're very heavy. Chance of unnecessary drama in your store may vary depending upon crew and management. Snitch culture is rampant. Lots of standing with little relief if you're a sandwich maker especially for long periods. No holiday pay for crew members. No bonuses or other incentives for crew members, which is very discouraging given this is another of those fast food restaurants that promotes a charity, which is good PR, but doesn't look after its people all that well.
