Mistakes, do happen! Just breathe! Sounds like the change in how you are scheduled, is the culprit, more than anything. Is there a pattern, to the scheduling? Or is it changing from week, to week?

I found myself, unnerved, at work, at my last location. There was a serious change to my routine, and it took, some time to make it work for me, and then it was 'noted' that my lack of 'enthusiasm' was showing. Job was being performed, and the person who filled my role, upon my promotion to a new location, heard it's just not the same, in that regard.

But, did I ever hear about it! Three times, to be exact! In my interview, for the managers position, in my job offer, and yes, in my final review under that job title.--one of my worst reviews. [Not to worry, in the employee remarks, I took accountability for that, and the wording used...Epic!!! very professionally stated, helped having been a manager before, helped having gone to the college I went to, helped listening to stories from mainly some of the men in my life, and didn't hurt concentrating my major with a couple law classes]

Oddly, enough, under my new position and title, I had my best review, ever!

Point being, structured-styled people, need consistency and structure. I had to adapt, to the major change. One of my supervisors, gave me a word of advice, on that, get finished, what I was used to finishing first, then prioritize the new tasks, after. i.e, put myself first, then the new stuff second. Not sure how that would translate, in your case, but I figured a way to squeeze minutes, that just don't exist on paper.

Do you have a phone calendar, can you track patterns of how these weekly shifts are lining up? Reminders, etc? Anything, to make your life easier?

Typos, can be from emotions coming to the surface, little distractions, I get that.

Hang in there, if people want to p*** and moan, behind your back, let them, they are probably frustrated with the employer, too!!
