Running Late From A vaccination: Telling Your Boss
If a vaccination runs over, a prompt update with a revised time keeps your manager informed and your day workable.
Say what you need, briefly
A jab is quick but usually clinic-hours only. Say when you'll step out and that you'll be back or make up the time.
Update your return time clearly
If you're running late back, send a short update as soon as you know, with a revised time and confirmation that nothing urgent is slipping. A prompt, factual update protects trust better than going quiet.
Example messages

I have a jab booked for [time]; I should be fine but may take it a little easy afterwards.
Mistakes to avoid
Don't go quiet and let people wonder. A short, prompt update with a new time is what's needed.
