This blog post is inspired by a conversation that started over coffee one morning with some friends.
Someone mentioned that a new hire at their workplace had taken time off – apparently, two people in their family had died in their first week on the job. And the reaction? Suspicion.
It just seemed a bit convenient, especially taking the Friday off before a long weekend…
Given my passion for workplace culture and how it impacts our mental health, when I heard this – I couldn’t hold back.
I paused and asked:
But… what if they really did have two deaths in the family this week?”
What if we came from a place of compassion – instead of immediately assuming the worst?
It wasn’t just the specifics that struck me. It was how quickly we default to doubt. How easily the benefit of the doubt is replaced by quiet judgement. And how socially accepted that has become – even in the face of someone grieving.
From there, the conversation turned to sick leave more broadly – the belief that Mondays and Fridays are always suspicious, and the fact that some companies require a doctor’s certificate if you’re sick on those days. That’s when the debate really began.
One person, a former business owner who said they’d managed over 120 staff, defended the policy:
Those are the most disruptive days for people to be away. You’ve got to stop people abusing it.
You’ve got to protect the business.
I understood the concern. But I saw it differently.
Because this is exactly why so many people are afraid to take a sick day. They know – even if they’re genuinely unwell – someone will assume otherwise. They’ll be met with a quiet joke, a suspicious glance, or a throwaway comment like, “took a sickie, did they?”
And that’s the real issue.
When “Sick Leave” Becomes a Dirty Word
There’s a cultural undercurrent in many workplaces where being sick is met with doubt before empathy. Especially if it happens on a Monday or a Friday.
And it’s not just formal policies that reinforce that mindset. It’s the day-to-day comments people make:
- “Must be nice to have a long weekend…”
- “Hope they enjoyed their ‘sick day’!”
- “Bit of a convenient time to get a cold, huh?”
Said with a smirk and a raised eyebrow…
Even when said jokingly, these remarks send a clear message:
We don’t really believe you.
This isn’t just about policy. It’s about culture. And culture is shaped by both systems and individuals.
Why Do Employers Target Mondays and Fridays?
Mondays and Fridays bookend the week. They’re high-pressure days in customer-facing or deadline-driven roles, and unexpected absences on those days can throw schedules into disarray.
But it’s not just about logistics – it’s also widely known that these are the days most commonly associated with ‘sickies.’ That perception, fair or not, often fuels blanket policies and snap judgements.
So some employers respond with blanket policies:
If you’re sick on a Monday or Friday, you need a doctor’s certificate.
It’s an attempt to prevent abuse.
But it sends a broader message:
We don’t trust you.
And while it might discourage a few people from faking it, it also discourages a lot more people from taking the time they genuinely need – especially when they’re dealing with mental health challenges, burnout, or invisible illness.
Trust Is Part of Good Planning
The argument that morning was framed around protecting the business. And fair enough – running a team, whether it’s five people or five hundred, means planning for absences.
But here’s the thing:
Whether or not someone provides a doctor’s certificate doesn’t actually solve the operational challenge.
If someone’s away – they’re away.
As an employer or team leader, it’s your responsibility to have a plan for that. That’s risk management. Whether you’ve got one employee or 100,000, the principle is the same:
- People will get sick.
- Some days will be more common than others.
- The business still has to function.
Certificates don’t prevent the absence – they just justify it.
The real question is:
Have you built enough resilience into your operations to handle the inevitable?
If not, that’s a planning issue – not a trust issue.
The Emotional Cost of “Prove It” Culture
Requiring a medical certificate for a single day of sick leave might seem like a harmless administrative safeguard. But in practice, it:
- Adds pressure to already unwell employees
- Costs money and time just to justify rest
- Signals mistrust, even toward people with no track record of misuse
- Undermines psychological safety in the workplace
And it fuels something even deeper: stigma.
The unspoken idea that being unwell is an inconvenience. That needing time off makes you unreliable. That unless you can prove your illness with paperwork, it doesn’t count.
This is exactly the kind of stigma we need to work harder to break.
Because when people feel ashamed or afraid to take sick leave – especially for mental health – they don’t speak up.
They hide it. They push through.
And eventually, they burn out.
That’s not a strong culture. That’s fear-based compliance.
Workplaces Don’t Just Reflect Society – They Shape It
When our conversation turned to the fact that workplace health and safety laws are changing – and that psychological safety is now just as much a responsibility for employers as physical safety – someone in the group said:
Well, mental health is a whole society challenge.
Absolutely. That’s true.
But workplaces don’t just reflect culture – they help create it.
Every workplace sends a message. When a company chooses to treat mental health as valid, respects sick leave without shame, and builds policies rooted in trust, it changes more than just the team. It changes what people expect – from themselves, from leadership, from work.
And when a company clings to outdated rules and distrustful practices, it reinforces the opposite.
Workplaces have a choice. They can contribute to the stigma – or help break it.
The Problem With the “Bad Apple” Excuse
The conversation also brought up the classic “bad apple” argument – the idea that policies like mandatory certificates are necessary because there will always be people who take advantage.
And yes, it’s true. There will always be people who abuse trust.
Someone who bends the rules. Someone who calls in sick when they’re not.
That’s the go-to justification for rigid policies:
We have to protect the business from the bad apples.
But here’s the part we don’t talk about enough:
One bad apple can spoil the bunch – but only if the environment allows it to fester.
If you leave apples in a sealed, airless box, one rotten one will spread its mould quickly. But if you store them in a well-ventilated basket, where each piece of fruit can breathe and be checked regularly, the rot is less likely to take hold – and it’s easier to spot and remove when it does.
Workplaces are the same.
If your culture is closed, controlling, and based on suspicion, one dishonest act can ripple through and corrode the whole environment. But in a culture of transparency, trust, and care, bad behaviour becomes the exception – not the norm. And it stands out quickly.
And if someone truly is a “bad apple”? They’ll usually reveal that in more ways than just a sick day. Poor intent and patterns of dishonesty don’t hide forever – and they should be dealt with, just as any consistent performance or behavioural issue would be.
If you build your policies around fear of the worst, you don’t just prevent problems – you prevent trust.
So What’s the Alternative?
You don’t need to throw structure out the window. But maybe it’s time to rethink the reflexive suspicion around sick leave.
- Instead of requiring certificates by default, apply them only when patterns emerge.
- Focus on open communication and resourcing, not policing.
- Invest in cross-training or coverage models so one absence doesn’t derail the entire week.
- Train leaders to support both physical and mental health absences without judgement.
- And most of all – trust your team until they give you a reason not to.
Because culture isn’t just what’s written in the policy. It’s what’s whispered in the lunchroom. It’s what gets rewarded, tolerated, or quietly judged. It’s what people feel when they say, “I’m not ok today.”
Final Thoughts: What Your Sick Leave Policy Says About You
If your first response to a sick day is suspicion, you’re not “just protecting the business” – you might be breaking the trust that keeps it strong.
True leadership isn’t about catching people out. It’s about creating a workplace where people don’t feel the need to hide.
And that starts with us – as individuals, as teams, and as decision-makers.
To be clear, I’m not denying the operational challenges. I understand that absences can disrupt business, and that patterns of misuse can’t be ignored. But those truths don’t cancel out the deeper one: how we respond to sick leave – especially mental health leave – says everything about the kind of culture we’re building.
You can acknowledge the risks while still choosing trust over control, compassion over suspicion.
So the next time someone takes a sick day, try replacing judgement with empathy.
You might just help shift the culture, one human moment at a time.
