“so either they don't care or she only does it with me.” Don’t assume that’s true. It rarely is
Take it to the boss. I’d actually be surprised if the boss doesn’t already know - they don’t need to be there physically to notice certain things.
I’ve been the boss in similar situations and I DID notice. Problem is it’s hard to fire someone for something so subtle and hard to prove so it takes time to build up that proof - but other employees formally noting their observations DOES help!
I would notice things like:
They were processing fewer orders than others (most modern tills staff have to be id’d on receipts/logged in to till)
This may seem weird and counter intuitive but if someone is very rarely complained about by customers - EVERYONE gets complaints sometimes because they’re not always down to poor performance you also get customers that love complaining so if they get hardy any at all that’s actually a red flag.
If responsibility for things like setting up till/cashing up is shared again who does it should be recorded and if they’re hardly ever doing that in comparison to others that’s a flag.
Seems overly simple but if they don’t know where items for the least popular jobs are kept! Eg the mop or how certain tasks should be carried out or how often (eg one job I had there was a piece of equipment needed a deep clean with specialised tools and cleaning fluids once a week - I noticed one employee was clueless even after 6 months of working there of how this task was done) - shows they hardly do them!
You get a feel for it if you’re a good boss in my opinion, and yes I know sadly not all bosses are good bosses! I hope I was.
Funnily enough a friend just shared a meme on Facebook the phrase is apt for this
Something like
“What puts off a good employee is seeing a bad employee tolerated”
Unfortunately true.
