Oh I completely know where you are coming from @Dbp I am experiencing the same thing at work (with the same response from management) and also experience the same symptoms as yourself, which are not helped by problems at work.
Staff have been cut back over the past 18 months or so and we are still expected to get the same amount of work done. My shifts are either 9 hours or 3 and a half hours long and in the short shift I am expected to get 9 hours work done......as if that is possible......and to make things worse you are constantly told all the bad things you are doing and no encouragement or even a good job muttered. I get home most shifts physically and mentally exhausted and usually vomit from feeling so stressed out for hours.......
I am trying to get another job but jobs are scarce here....I am casual at the moment and want either part or full time work for extra job security etc.....but they are few and far between where I am.
I wish I had some words of wisdom for you but sadly I do not........it is really frustrating when money becomes more important than our mental and physical health...........I am sick of being ruled by money...............
I wish you all the best in your endeavour in seeking other employment and I hope you can cope in the mean time.......
Blessings to you and welcome to the forum........
