# Actual `Actuals` capture the worked hours for an `Employee` during a completed work shift. This data is used to provide insights into actual worked hours compared to contractual hours, and also helps steer the optimization algorithm towards creating a balanced work week that fulfills contractual hours without significant undershooting or overshooting. By their nature, `Actuals` should always represent completed work shifts and therefore should always be in the past, adding `Actuals` that end in the future could lead to undesired behaviour.
