A pressure measurement can further be described by the type of measurement being performed. There are three types of pressure measurements: absolute, gauge, and differential. Absolute pressure measurement is measured relative to a vacuum (Figure 2).
For example, the median tenure of workers ages 55 to 64 (10.1 years) was more than three times that of workers ages 25 to 34 years (2.8 years). Also, a larger proportion of older workers than younger workers had 10 years or more of tenure.
Job seekers typically face age restrictions up until the age of 21 or 22. Many entry-level positions require young workers to stand at least 16 in order to gain employment, while others require applicants to be at least 18 years old upon hire.
