Day in lieu, accrued leave & year-end planning. Are you familiar with this HR vocabulary?

November and December are particularly busy months in many organisations. Teams are wrapping up projects, coordinating holiday schedules, reviewing outstanding leave balances and arranging cover for the festive period.
In an international workplace, knowing how to say annual leave or day off is not always enough. If you want to communicate confidently and professionally, it’s worth expanding your HR and Business English vocabulary.
Let’s start with day in lieu – a day off granted in exchange for working on another day. But there’s much more to explore!
1. Advanced HR vocabulary – level up your English!
🔸 accrued leave – leave accumulated over a period of time
🔸 untaken leave – annual leave that has not been used
🔸 carry forward / carry over leave – transfer unused leave to the next leave year
🔸 forfeit unused leave – lose the right to unused leave
🔸 leave entitlement – the amount of leave an employee is entitled to
🔸 compensatory time off – time off granted as compensation for additional work
🔸 operational requirements – the needs and demands of business operations
🔸 staffing constraints – limitations related to staff availability
🔸 year-end leave balance – the remaining leave balance at the end of the year
🔸 subject to managerial approval – depending on approval from a manager
2. Sound more professional – useful expressions in context
Here are some expressions you might come across in HR correspondence, internal communications or conversations with your manager:
🔸 I still have a substantial amount of accrued leave to use before the end of the year.
🔸 Could you clarify whether any unused annual leave can be carried forward into the next leave year?
🔸 Due to operational requirements, we may need to restrict leave requests during the final week of December.
🔸 I’d like to enquire about taking compensatory time off for the additional hours worked during the public holiday.
🔸Please ensure that all outstanding leave balances are reviewed before the year-end deadline.
3. A little linguistic challenge
Do you know the difference between day in lieu and time off in lieu (TOIL)?
Although both expressions refer to time off granted as compensation, they are not entirely interchangeable.
🔸 Day in lieu – usually a specific day off granted in exchange for working on another day, for example, a public holiday.
🔸 Time off in lieu (TOIL) – time off granted instead of payment for additional hours worked.
In American Business English, you may also come across the term compensatory time off, or simply comp time.
4. One more thing before the year ends…
Here’s a question worth asking yourself before the festive season begins:
Have you managed to use your annual leave entitlement, or are you still trying to squeeze in a few days off before the year ends?
After all, talking about holidays can be a great opportunity to practise your English at C1 level!
Remember: Leave policies and the rules governing unused holiday entitlement vary between countries and employers. Always check the applicable regulations and internal company policies.
