Letter to a Colleague Thanking Them for Covering a Shift

The question

How to approach this semi-formal letter question

A semi-formal letter goes to someone you know a little, such as a neighbour or a teacher. Be polite but warmer than in a formal letter.

1. Use the person's name (Dear Mr Hall,) and a friendly but respectful opening.
2. Cover each bullet point in its own paragraph.
3. Some contractions are fine; keep the language clear and courteous.
4. Close with "Yours sincerely," and your name.

How to plan this answer

Structure

1. Opening: 'Dear' and your colleague's name, then an immediate line of thanks for covering your shift.
2. Paragraph 2: briefly explain the family emergency and why you had to leave work early on a busy day.
3. Paragraph 3: describe how their help made a difference to you and to the team.
4. Paragraph 4: offer to cover a shift for them in future, naming a day or type of shift that would suit you.
5. Closing: thank them again and sign off 'Kind regards' or 'Best wishes'.

Points to cover

• Emergency: a family member was taken into hospital, and you had to leave at midday on a busy Thursday.
• Impact: the shift stayed fully staffed, customers were served without delay, and you could focus on your family.
• Their approach: they stepped in without being asked, even though you know them only a little.
• Offer: cover their next Saturday shift, or a late shift on a day when they have a commitment.
• Recognition: mention that you told your manager about their help, or offer to buy them a coffee as a thank-you.

Useful vocabulary

• I wanted to thank you for: I wanted to thank you for covering my shift last Thursday.
• I am very grateful for: I am very grateful for the way you stepped in at short notice.
• covering my shift: Thank you for covering my shift when I was called away.
• stepped in: You stepped in without being asked, which meant a great deal to me.
• at very short notice: You agreed to help at very short notice, which I really appreciated.
• It made a real difference: Your help made a real difference to my family and to the team.
• I'd be happy to return the favour: I'd be happy to return the favour and cover a shift for you in the future.
• Please let me know if there is ever a time I can help: Please let me know if there is ever a time I can help you.
• in a difficult situation: You helped me when I was in a difficult situation.

Common mistakes

• Thanking your colleague without describing how their help changed the situation, which the second bullet requires.
• Writing as though you know them well, with words such as 'mate' or 'buddy', when the prompt says you know them only a little.
• Offering vague help, such as 'I'll help sometime', instead of naming a day or type of shift.
• Giving a long and detailed account of the emergency, when a brief mention is enough.
• Omitting the sign-off phrase, such as 'Kind regards' or 'Best wishes', that the task asks for.

Examiner tip: Name what your colleague did and what it changed for you, then make a specific offer, so the letter sounds sincere rather than like a formality.
