In the context of employment law, the period of time employees must have worked continuously for an employer in order to be eligible for certain statutory rights. For example, employees must usually have worked for one year to claim unfair dismissal, one month to request a written statement of changes in terms and two years to be eligible for time off to look for other work or for training if under notice for redundancy.
