Kontras
In order to be hired full-time, in most situations, you must start as a part-time employee working evenings without any benefits at all for the first year. After that vacation is accrued based upon hours worked for the week. Sometimes evening people are not treated with the same respect as full-time day employees are. Generally, full-time positions are filled from part-time workers only as a position opens up. In order to establish a career, you must wait until a full-time position is available. This can possibly cut into valuable time establishing a career.
