One of the recent trends in recycling right now is all-in-one recycling. All the paper, plastic, glass, and metal waste goes into one recycle bin, which is sorted at the factory. The argument is that it requires fewer trucks to pick it all up.
Construction work is usually seasonal. Many crops can only be grown during specific times during the year. Retail clerk positions are often seasonal. Package delivery personnel are often hired during the holidays.
A seasonal job lacks the security and benefits of regular employment, but can nevertheless be a good deal in the right circumstances. Students often take seasonal jobs as a way of gaining some work experience, which can help fill out a resume and act as evidence of drive and dedication.
