Where to begin? Little to no training, incompetent and ineffectual management, difficult and stressful shifts in situations you'll not have been educated or orientated in or to. Workplace bullying by colleagues, managers and clients.Difficult and dangerous workplaces and roles with no support and little information, however, you will be held responsible for any and all issues, despite your lack of Knowledge or training in these situations. Stressful and long, lonely shifts punctuated by having to clean soiled clients and bouts of physical violence. You may or may not be relived at the end of your 24 hour shift (it's a bit like lotto, but the prize is more sole destroying work)!
It could be a worthy and rewarding role, helping those with a disability live a good and productive life, however, red tape, politically correct bullsh*t and severely limited funds (not to mention a completely incompetent management structure) stifle your ability to do any good at all!
Also, there is a good chance you will assaulted and or injured frequently, so, there's that to look forward to.
