Can you write me an polite E-Mail to inform my colleagues that I'll be sick for the entire week, please.
Dear colleagues,

I hope this email finds you all well. Unfortunately, I wanted to let you know that due to unexpected circumstances, I will be unable to come to work this week as I am feeling unwell.

I apologize for any inconvenience this may cause, and I will do my best to catch up on any missed work when I return. In the meantime, please feel free to reach out to me if there are any urgent matters that require my attention and I will do my best to respond as soon as I am able.

Thank you for your understanding and support during this time. I look forward to rejoining the team as soon as I am able.

Best regards,

[Your Name]
