L-DOPA (/ËÉlËdoÊpÉ/ or /ËlÉvoÊËdoÊpÉ/) (alt., L-3,4-dihydroxyphenylalanine) is a chemical that is made and used as part of the normal biology of humans, some animals and plants. Some animals and humans make it via biosynthesis from the amino acid L-tyrosine.
The maximum number of hours most employees can be required to work in a day is eight hours or the number of hours in an established regular workday, if it is longer than eight hours. The only way the daily maximum can be exceeded is by written agreement between the employee and employer.
However, even among full-time workers (those usually working 35 hours or more per week), men worked longer than women--8.4 hours, compared with 7.8 hours. (See table 4.) --One-third of employed persons spent some time working on an average weekend day.
