💬 Message Templates
📱 WhatsApp — Standard Sick Day 🔊
Best for: Common colds, general unwellness.
“Hi [Name], I’m afraid I woke up feeling unwell today and won’t be able to come in for my shift. I am going to rest and will keep you updated on how I feel tomorrow. Apologies for the inconvenience.”
Plain-English explanation: Clear, polite, and sets expectations for a follow-up the next day.
📱 WhatsApp — Stomach Bug / Contagious Illness 🔊
Best for: Illnesses where you legally must stay away from the workplace.
“Morning [Name], I’ve unfortunately caught a stomach bug and am not fit for work today. Since it might be contagious, I’ll need to stay home and recover. I’ll let you know tomorrow how I’m doing.”
Plain-English explanation: Explains why staying away is necessary, not just preferred.
💬 SMS — Short & Direct (Shift Workers) 🔊
Best for: Quick texts when you don’t have time to write a long message.
“Hi [Name], it’s [Your Name]. I am unwell today and cannot make it to my [Time] shift. Sorry for the short notice, I will update you tomorrow.”
Plain-English explanation: Short and to the point — ideal when texting between sick spells.
📞 Phone Call — Standard Script 🔊
Best for: Workplaces that require a call instead of a text message.
You: “Hi [Name], it’s [Your Name].” → Manager: “Hi [Your Name], how are you?” → You: “Actually, I’m calling because I’ve woken up feeling quite unwell. I’m afraid I won’t be able to come in for my shift today. I need to take a sick day to rest.”
Plain-English explanation: A simple, natural script you can practise saying out loud before you call.
🚨 Emergency / Short Notice 🔊
Best for: Sudden illness or medical emergencies.
“Hi [Name], sincere apologies for the extremely short notice, but I’ve had a medical emergency and am unable to attend work today. I will update you as soon as I have more information.”
Plain-English explanation: Acknowledges the short notice and promises a follow-up once you know more.
🎬 Real Workplace Scenario
🔊 Play Scenario — Sending a WhatsApp message at 6am before an early shift
You: Hi Tom, I’m afraid I woke up feeling unwell today and won’t be able to come in for my 7am shift. I’m going to rest and will keep you updated on how I feel tomorrow.
Tom (Manager): Thanks for letting me know so early, get well soon.
You: Thank you, I will.
💡 Sending the message as soon as you wake up — rather than waiting until just before your shift — gives your manager time to find cover.

🇬🇧 UK Workplace Tip
Direct translations from other languages can sometimes sound too blunt in UK English. For example, “I am sick” can sound abrupt — “I’m afraid I’m unwell today” is softer and more natural in a British workplace.
💼 Expert Note
Save one or two of these templates in your phone’s notes app so they’re ready whenever you need them. A clear, early message — even a short one — shows your manager that you’re being responsible, not just absent.
❓ Frequently Asked Questions
Can I just send a WhatsApp, or do I have to call?
This depends entirely on your company’s sickness policy. Many modern workplaces accept WhatsApp or SMS, but some strict policies require a phone call. Always check your handbook.
Do I need to reply to work messages while off sick?
No. If you’re off sick, you’re not expected to work. You can set an out-of-office auto-reply on your email if needed.
What if I don’t know my manager’s preferred contact method?
If you’re unsure, a phone call is usually the safest first choice for your very first sick day — after that, ask what they prefer for future occasions.
