Quick show of hands – who remembers their worst manager?
I’m betting you learned almost as much from them as you did from your best one, right? My best manager gave me the skills and confidence to become an excellent HR consultant. Challenged me, gave me difficult feedback, encouraged me, invested in my development.
My worst? No induction, no one-to-ones, and I felt completely ignored. And the absolute worst part of working with that manager? Well, he was an addict and I once had to clean up his poo. Yes, you read that right.
I’m writing this at Halloween time, so since it’s the season for spine-chilling stories, I thought I’d share some workplace horror stories with you. But unlike your typical ghost story, these nightmares are absolutely real – and they’re happening in businesses every single day.
These aren’t just cautionary tales to give you goosebumps. They’re expensive disasters that could have been completely prevented with better management. So grab a cup of tea (or something stronger), and let me tell you about the management monsters that are costing businesses thousands.
The stats that should terrify every business owner
Before I dive into my horror stories, let me share some statistics that are scarier than any Halloween movie:
- 75% of employees who quit do so because of their manager, not their job or company
- Nearly 1 in 2 employees have left a job to get away from a bad boss
- 84% of workers say poorly trained managers create unnecessary stress
- 82% of managers are “accidental” – thrust into roles without proper training
If those numbers don’t scare you into getting serious with your manager training, nothing will.
Horror story #1: The invisible manager
Jane started in a busy sales office, tasked with typing up menus for events. What her manager didn’t know? Jane was dyslexic.
On her very first day, Jane overheard colleagues mocking another dyslexic employee. Naturally, she decided to keep quiet about her own struggles rather than face the same ridicule.
Week after week, Jane made mistakes. Her manager noticed but never bothered to ask why or offer support. No check-ins, no “How are you getting on?”, no curiosity about what might be causing the errors.
Jane failed her probation.
Here’s the really horrifying part: when Jane eventually opened up to HR during her exit interview, she explained that a couple of simple adjustments would have set her up for success. Recording training sessions so she could listen back at home. Written instructions instead of verbal ones. Basic stuff that would have cost – you guessed it – nothing.
The real cost: Recruitment fees for her replacement, lost productivity during her employment, wasted training time, and the opportunity cost of losing someone who could have been brilliant with minimal support!
The prevention: A manager who actually managed. Someone who checked in, asked questions, was proactive in the probation period, and created an environment where people felt safe to ask for help.
Horror story #2: The “you’ll figure it out” nightmare
Alan’s first day at his new job was a masterclass in how not to onboard someone.
He spent his entire first day battling with IT just to get a login. No structured training plan, no buddy system, no proper introduction to the team or processes.
When he finally got access to the systems, someone casually told him, “You’ve done this kind of work before, so you can just get on with it.”
Alan quit within a week.
This wasn’t a skills issue; Alan was perfectly capable of doing the job. This was a complete failure of onboarding and management support.
The real cost: All the time and money invested in recruiting Alan, plus starting the whole recruitment process again. Not to mention the message it sent to other team members about how the company values its people.
The prevention: A proper induction process. Basic human decency. A manager who understood that even experienced people need support when they’re learning new systems, processes, and team dynamics.
Horror story #3: The Christmas party catastrophe
This one’s particularly relevant given that party season is nearly upon us.
A company director sexually harassed an employee at the Christmas party. Because he was a shareholder, dismissal wasn’t straightforward. The situation required not one, but two costly mediations to resolve.
The employee wanted to stay (much to the relief of the company), and the director was genuinely committed to making things right, which is why mediation worked.
But it was still months of stress, damaged relationships, and significant costs that could have been completely avoided.
The real cost: Two mediation sessions, ongoing tension in the workplace, potential reputational damage, and the very real risk of a sexual harassment and constructive dismissal claim if it hadn’t been resolved.
The prevention: Proper boundaries training, clear expectations about behaviour at work events, and managers who understand their responsibilities don’t disappear just because there’s alcohol involved.
The Maslow reality check
Remember Maslow’s hierarchy of needs from Psychology 101? All those shiny benefit packages – wellness programs, Employee Assistance Programs (EAPs), free lunches – they’re at the top of the pyramid. Self-fulfilment stuff.
But that stuff doesn’t work if the base needs – safety, belonging, respect – are shaky.
Long before I worked in HR myself, I once worked reception at a hotel during a massive system outage. I was on my 36th hour of a shift (yes, really), and the HR manager came round with a box of doughnuts. In that moment, what I needed wasn’t a doughnut. It was a proper meal and someone to take over so I could sleep.
That’s Maslow’s hierarchy in action; until the basics are met, the perks don’t matter. Doughnuts don’t fix bad management!
A good manager helps employees feel safe, respected, and seen. Without that foundation, no EAP, mental health fund, or free yoga class can make much difference.
A common horror – management incompetence
What links all these horror stories? Poor management.
Managers who don’t know how to:
- Create psychologically safe environments
- Conduct proper check-ins and provide support
- Set clear expectations and boundaries
- Recognise when someone is struggling
- Have difficult conversations early, before they become crises
And here’s the thing – it’s often not entirely their fault. According to the Chartered Management Institute, 82% of managers are “accidental” – thrust into management roles without proper training.
Most businesses promote technically competent people and then expect them to just… manage. Without training, without support, without any real understanding of what good management actually looks like.
Gallup research shows that companies get the wrong managers 82% of the time, and only 10% of people have the natural talent to be great leaders – we’re literally setting people up to fail!
The Employment Rights Bill makes this urgent
With day-one unfair dismissal rights likely coming down the pipeline, businesses with unprepared managers are walking into very expensive territory.
If your managers can’t conduct proper probationary review meetings, handle underperformance fairly, or create supportive environments where issues are addressed early, you’re going to find yourself facing expensive tribunal claims much more frequently.
The current two-year protection period has masked a lot of management incompetence. When that disappears, every hiring decision and every management interaction becomes critical.
The cost of management incompetence
Let’s talk numbers, because the financial impact of bad managers goes far beyond the obvious costs:
Direct costs:
- Recruitment fees for failed hires
- Legal fees when things go wrong
- Tribunal awards and compensation
- Mediation and investigation costs
Hidden costs:
- Lost productivity from disengaged teams
- Absence costs from stressed-out employees
- The time senior leaders spend firefighting
- Reputational damage affecting future recruitment
Opportunity costs:
- The performance improvements you never see
- The innovations that don’t happen
- The customer relationships that suffer
- The growth that gets delayed
I’ve seen businesses spend more on recruitment churn in a single year than it would cost to properly train all their managers. It’s madness.
Your management reality check
Here’s a question for you: What formal training do your managers receive on actually managing people?
Not technical training. Not product knowledge. Not systems training.
Training on how to:
- Conduct effective one-to-ones
- Have performance conversations
- Support struggling team members
- Handle conflicts early
- Create inclusive, psychologically safe environments
If you’re drawing a blank right now, you’re not alone. Most businesses are in the same boat. But with the employment law landscape changing rapidly, this isn’t something you can afford to ignore much longer.
Don’t become my next horror story
Here’s my challenge to you:
Before you spend another pound on shiny benefits packages, ask yourself one question – how capable are my managers?
Because the truth is, people don’t leave their jobs, they leave their managers. And people don’t thrive because of free yoga; they thrive because they feel safe, supported, and seen by the person they report to every day.
The tragedy of all these horror stories is that they were completely preventable. Jane could have thrived with proper support. Alan could have become a valuable team member with decent onboarding. The Christmas party incident could have been avoided with clear boundaries and proper training.
Instead, these businesses paid far more in recruitment, legal fees, and damage control than it would have cost to get management right in the first place.
As we head into 2026, with new employment rights likely to make everything more complex and expensive, investing in management capability isn’t optional, it’s essential for survival.
Your managers are either your secret weapon or your hidden liability. There’s no middle ground.
Ready to turn yours into a competitive advantage? Train them in empathy, giving feedback, mental health awareness. Give them the tools to manage one-to-ones effectively, so they know what to do when someone bursts into tears. Teach them to spot quiet quitting and how to build credibility and trust.
Because when managers get it right, everything else – performance, engagement, wellbeing – falls into place.
Don’t wait until you become the subject of my next horror story. Let’s chat about how proper management training could transform your business before these nightmares become your reality.
Because prevention beats panic every single time.
Sweet dreams! ????
