Pulled up for “picking on someone at work”.

Wind your own neck in. If you had bothered to read this through the managers don't want to manage and have told the workers they are mature enough to sort out their own problems. When you have shown the same people how to do something for the umpteenth time and despite suggesting that they write it down, they don't, and you can't get on with your own work because they haven't done what they were supposed to do first and training other members of staff is not in your job description is it any wonder that people get just a tad pissed off. The OP is not in a management or training position and yet is expected to manage and train and when she does she gets accused of "picking on" people who are supposed to be adults. We are talking about graduates not 16 year olds straight out of secondary school. God knows what they graduated in, definitely not common sense or work ethic.

Considering your considerable experience, you have clearly handled this very badly!
It’s not your job to comment or correct others’ work. You do your job, and any issues from
others you report to your line manager to deal with.
If you’ve been tackling the individuals yourself, you are ripe for a bullying charge.
Wind your neck in.

I find chatGBT really helpful in giving good, clear step by step guidance to workplace issues. You do need to go back into work and resolve it in a professional manner with your managers. Good luck.

That assumes that her company has regular supervisions. Where I work now does, but I've been in many places where that isn't a requirement.

But her supervisors don't want to supervise and the managers don't want to manage, they want the staff to sort things out themselves. In trying to do this and getting nowhere, she let off steam, not at the slackers, but with her colleagues who are in the same situation and has been pulled up about it. This is a no-win situation for her.

She’d have to raise it in supervision then. If she tells the powers that be she can’t do her job because of the slackers then it will get sorted quite quickly probably. It would be a performance issue.

One of the things about your first job is that you don't just learn the job, you learn about how to operate in the workplace.

If these colleagues have just left school, they will have no clue whatsoever about how to behave at work.

I'm going to take a wild stab that after 6 months in the office, being asked to behave in certain ways and having the example of experienced office staff to follow (e.g. actually cleaning up after yourself), these people DO have a clue even if they didn't to start with. It can't be ignorance after that amount of time, must purely be idleness and/or entitlement.

If these colleagues have just left school, they will have no clue whatsoever about how to behave at work.

Seems like they have no clue how to behave, full stop. Do what you are asked and clean up after yourself are primary school level requirements.

Did none of them ever have Saturday jobs or holiday jobs?

And since when was it the employer's job to tell them where to go for lunch? This sort of thing just perpetuates the helplessness and expectation of spoonfeeding. You find out that sort of thing through talking to your colleagues, or going for a walk in your lunch break.

Very simple don't do it. Do what you are paid to do. The management will see exactly what is happening. Dishes bring your own keep in locker and ignore their mess

Pass your complaints up the line. Let your manager manage this. That is their job. You have even more reason to do this now. Stop cleaning up after grown adults. You aren't their mother. Let the bin overflow. Leave the cups in the sink.

That's where a proper induction process is absolutely essential and your managaement is shit for not having one.

Best thing you could do is offer to draw up an induction program with instructions on how to do stuff, what the norm is, stuff like toilets, lunch, smoking breaks etc, where the nice sandwich bars are, where the local park is to sit in at lunchtime, code for the photocopier, what each department does, where the stationery cupboard is etc.

As someone else said go to them with a solution, not a problem.

Not every workplace has a cleaner you know, and those which do sometimes have a limit on what tasks they carry out e.g. empty bins, vacuum floor, wipe over desks, not all do the washing up & cleaning the kitchen.

And maybe, just maybe, the OP feels sick having to use a kitchen covered in other people's rotting stinking waste & cups growing mould - yes, I have worked in places where cups got left & grow a good inch or so of greenish mould on top of the dregs left by the previous user.

I don't understand why you would be doing their washing up or clearing up after them, just leave it. You don't have a parent or housemate relationship with them, leave it to the cleaner. If the cleaner wants to complain or it goes around in a passive aggressive email then let them.

As an employer I would see it as a huge negative, it looks like you're finding excuses to avoid work and I'm not paying you to do the office's washing up.

There is never a good reason for "losing it" at work, where is your professionalism?

Are you serious 1mabon !!! You clearly work either alone or in cloud cuckoo land!! People as a rule don't "lose it" without extreme provocation. Its nice you've never encountered that but I actually finally retired from my job before I was sacked as I was truly in danger of punching a very vile horrible colleague, with whom I had "lost it" on more than one occasion. She was so vile even line managers were afraid of her. I did manage to instigate a formal complaint against her to those very much further up the ladder before I left though, which HAD to be followed up. She left the job after that, but I'd had enough by then.

OP, I'd document EVERYTHING you know about these lazy arses, and ALWAYS put everything in writing, e.g instructions to them about how to do things, 'polite reminders' of overdue work, EVERYTHING... then you have proof you've tried to help but they're not engaging. I sympathise... been there !!!!

How did you get on yesterday @ThunderRoadRunner ?

I get the impression that OP can't do her work until the other stuff is completed. Sort of like you can't put the roof on a house until the walls are built.

Just don’t do their work?

If anyone forgot their pass at work they had to ask for a visitors pass and sign for it. We weren't allowed to share passes.

Yes, I hope so too. 🤞

Go above your managers head to their manager if they aren't dealing with this.

When I manage people I don't want to be included in every email they send I have enough in my inbox to be getting on with, I am not back at school I expect staff to not need to me micromanaged

Also this. Useless nobbers.

Just say you can't help any more. Don't say I've told you loads of times you idiot, just be 'too busy' with something else. Then if/when they involve your manager and say you won't help them you can just say - very sorry manager I was very busy but also I'm confused as I showed them 5 times how to do X, so actually not even sure they needed my help.

Hope today is going well for you @ThunderRoadRunner .
