Most SMEs get these three things wrong about sickness leave and they cost them the most money every year.
"I cannot ask for a doctor's note in the first week."
You cannot ask for a fit note. You absolutely can ask for a completed self-certification form, and you should, every single time. Silence in the first week is the more expensive option.
"Self-certification is basically a joke."
It is a legal document. If it turns out to be untrue, that is a disciplinary matter. If you never ask for one, you have quietly waived your own protection.
"I can dismiss them after X days."
There is no magic number. Anyone giving you one is making it up. Long-term sickness dismissals need capability procedures, medical evidence, reasonable adjustments, and proper consultation. Get it wrong once and it will be the most expensive process your business has ever run.
The truth underneath all three.
Sickness absence is one of the most emotionally charged bits of HR, and most managers avoid it because they are worried about seeming heartless. So they say nothing. Do nothing. Hope it resolves itself. And inherit a much bigger problem three months later.
Kindness and process are not opposites. The kindest thing you can do for a sick employee is have a warm, curious conversation early, with a manager who actually knows what they are doing.
And if you are the one currently off sick, reading this on your sofa with a cup of tea and a slight sense of guilt, this is your reminder that you are allowed to rest.
Actually rest. Your work will wait. The people who love you would rather you got properly better than half-answered emails in your dressing gown.
Look after yourself. Everything else can wait until Monday.
