The concept of time off in lieu (TOIL) is an alternative to paying overtime for work done in addition to regular hours. For example, a worker contracted to do 8 hours in a day may be required to work an extra 3 hours.

Rather than paying overtime rates, the business may offer the employee to have 3 hours off on another day while still getting paid for the full day. This a good thing to practice as an organisation; this is because the employee will be rest assured that the extra hours they are working are taken into consideration by the employer, therefore it will encourage to do more.
