Pay barely above minimum wage, long shifts, compulsory overtime, shifts changed with as little as 24 hours notice, aggressive interrogation if you dare to be too ill to work, incompetent management who shift blame onto their subordinates, more red tape than you would ever believe possible (there is literally a form for everything - one for replacing jugs of water / juice, one for cleaning something, and for the lucky senior care staff, a form to confirm all the other forms have been signed!) resulting in more time spent pen pushing than actually caring for the residents, constantly short staffed due to high turnover of staff (the endless cycle of doom), formal investigation / disciplinary action taken for the most minor of oversights (e.g. forgetting to sign one of the aforementioned forms), no performance related bonuses (only a 'Kindness in Care' award for great performance, which means having your photo displayed in a nice little frame for a while), condescending and sarcastic management style that involves berating you in front of your colleagues and making you feel like you're at school again...
I could go on forever, but if you're still insane enough to consider working for HC One after reading all of the above, the best of luck to you and don't forget to hand in your uniform when you inevitably leave.
