Well I have worked for these so called tirants, and I would like to say that I disbelieve you. If you are a reader of this page, you will know that I have worked for the company for over 2 and a half years, and I have minor, if any complaints about the way staff are treated.
In my time with Hungry Jacks, I have worked with over 50 managers, and have never heard one of them abuse a staff member without good reason. Sure, I have heard managers scream at staff, and call them a lot of names, but not without the staff member having done something to deserve it.
I have been involved with interviews and hiring process, and rudeness is something that is NOT looked for. A rude person once applied for a job at my store, and after the interview, we literally tore up the interview sheet and put it in the bin.
The company is in a very stable condition at the moment, and is not, as you say, rooted. You ARE complaining about the company, so yes, that makes you the complainants.
To all hungry jacks staff that read this page, I would like to suggest something that is stated in your Crew Handbook. If you have a problem, take it up with your Store Manager. If you aren't satisfied, see your District Manger, then your state manager, then the national manager if you choose. Don't leave the store if you're unhappy.
