I've worked at the same place for five years.
I'm looking for work but it is a high unemployment rural area so to find something is rare enough but due to childcare I need certain days on and off so I can both look after my dd and earn enough money for us to live.
When I got this job I had to obviously let them know my experience and qualifications. I had experience but I have no qualifications
I won't let it hold me back, I perform well and do the job without a hitch. I am often the most senior person in the workplace unless my manager is in.
My manager is a dick. Every week there's a nasty comment. Last week it was
"We need to do a stock count, co worker name can you start counting up x and y there should be about 80 I don't want my name to do it as she can't count beyond 10"
Always something like that and always in front of other people. To the point where my co workers are often surprised that yes I can count and do everything else when manager fucks off on holiday for 3 weeks at 2 days notice
I can count fine, as well as read, understand and make graphs and charts, do basic algebra, add, subtract and divide.
Im also trusted to count cash and do a weekly bank run, but I'm not trusted to count to approximately 80? 
I'm by no means an expert and if I sat a maths GCSE today I'd probably fail but it's perfectly sufficient for my job!
Aibu to wish people wouldn't take the piss?
