Lactulose is used as a laxative to treat constipation. In the colon, lactulose is broken down by bacteria into products that help to draw water into the colon, which softens the stool.
If you work full-time, then you are entitled to all the benefits offered to employees by your employer for full-time workers. The definition of full-time, however, varies -- some companies may consider 37.5 to 40 hours as full-time with anything less categorized as part-time. In the state of Texas, however, a full-time worker is anyone who works at least 30 hours per week, according to the Texas Department of Insurance.
Part time is a label. I worked a job where they said I was part time, to keep me from getting benefits, even though I was working 40 hours. Since benefits are a company choice and not required by law, they can set the rules of how many hours you have to work to qualify for benefits. Most companies set it at 32, but I've seen better places say anything over 20 qualifies for benefits. The employer decides what is part time.
