3 doctors agreed: Muscle spasm: This could be a muscle spasm. I have heard this description many times before. Hernias do not occur in the upper abdomen by the rib cage. They do occur in the middle. The muscle spasm can cause severe pain, and ball up, mimicking a hernia.
Generally, working part time is considered working anything less than what your employer considers full time. The Bureau of Labor Statistics defines part-time status as working on average between one and 34 hours per week. In the end, it is up to the employer to decide how many hours is part time and how many would make the job a full-time position. The Department of Labor does not differentiate between the two statuses.
Maximum weekly hours. An employee can work a maximum of 38 ordinary hours in a week. The time of the day ordinary hours are worked is called the spread of hours (eg. between 7am - 7pm). Time worked outside the spread of ordinary hours can attract overtime rates.
