Local retailers are optimistic about this holiday season, and to prepare for the influx of customers they're hiring a whole slew of temporary workers.

The National Retail Federation predicts that sales from this November and December could increase by as much as 4.1 percent as compared with last year's performance, and that's excluding automobile, gas and restaurant sales.

Collectively, American retailers are expecting to add 800,000 seasonal employees, which would be the largest number of holiday workers hired in 15 years.

Large retailers like Wal-Mart and Kohl's are significantly increasing the number of employees at their stores, while others, like Target, are predicting higher online sales and so are not as concerned with brick-and-mortar staffing.

"We just always have the business for it," business director Jamie Thrower told the Seattle Post-Intelligencer. "So, we'll probably keep 90 percent of them. For one this year, our growth has enabled that. In years past, it's been attributed to some turnover. But this year our turnover has dropped and we've been able to keep more of our employees long-term. We just have a need for those jobs this year because of our growth."

Retailers are hoping that the additional jobs will help the reviving economy and deliver a successful holiday season in terms of revenue.

When your store is preparing for the holidays, it's important to train your seasonal employees on how to use your POS system correctly. It's also a good idea to check to see if your card processing software needs to be updated or switched out before you're inundated with winter sales. A high quality software can save employees valuable time by keeping track of inventory, orders and purchases of all kinds.
