NEW YORK (AP) — Chris Mann learned it's better to hire help for the November and December holidays while people in many parts of the U.S. are still wearing shorts and tank tops.

Thin staffing at many small businesses makes the process of assimilating seasonal workers harder than at larger companies. David Bolotsky starts hiring in August to be sure he gets seasonal staffers who have a good attitude, work well with others and are willing to commit to a job not likely to lead to year-round employment. The owner of Uncommon Goods, an online retailer of clothing and home goods, brings in recruiters to screen prospective staffers and try to weed out ones who look like they won't be a good fit. Mohu, a manufacturer of high-definition TV antennas, usually has a surge in orders around the holidays when people buy new TVs.
