Oluwapelumi Dada Co-founder & CEO, Sorce1 min read

The modern playbook for calling in sick:

When to notify

Before your shift starts. Earlier the better.

What to say

"Out sick today, will check Slack if urgent. Back tomorrow."

That's it.

Channel

  • Slack / Teams, standard for modern offices.
  • Email, also fine.
  • Text, fine for managers you message regularly.
  • Phone call, traditional industries, shifts, healthcare.

Match what your team does.

What to avoid

  • Long explanations
  • Multiple apology messages
  • Posting on social media that day
  • Calling out repeatedly without explanation

Returning to work

  • Wait until you're not contagious.
  • Be ready to function, coming back too early hurts you and your team.
  • Brief catch-up message: "Back today, what did I miss?"

When you're chronically sick

If you're calling in sick frequently due to chronic illness:

  • Talk to HR about accommodations
  • Check if FMLA applies
  • Document your conditions formally

Don't suffer through it silently.

Do I need a doctor's note?

When you're not contagious and can do your job. Stay home longer if you're contagious, your colleagues will thank you.
