You will not find support from higher ups. Complaints will go unresolved and you'll be asked to handle a workload that is extremely stressful and overwhelming. You can ask for help, but be sure you understand that in asking for help you are essentially putting a target on your back. Best advise to stay in the good graces of everyone is to keep your head down, get some of your work done during your unpaid lunch and don't ever try to understand why they are asking you to do the things they are asking you to do.
