Seniority is the state of being older or placed in a higher position of status relative to another individual, group, or organization. For example, one employee may be senior to another either by role or rank (such as a CEO vice a manager), or by having more years served within the organization (such as one peer being accorded greater status over another due to amount of time in). The term "seniority" can apply to either concept or both concurrently.

thumb|Contemporary time sheet A timesheet (or time sheet) is a method for recording the amount of a worker's time spent on each job. Traditionally a sheet of paper with the data arranged in tabular format, a timesheet is now often a digital document or spreadsheet. The time cards stamped by time clocks can serve as a timesheet or provide the data to fill one. These, too, are now often digital. Timesheets came into use in the 19th century as time books. To record time in a more granular fashion, time-tracking software may be used.
