Seasonal jobs
Many businesses are looking to add part-time workers to meet their seasonal demand. Retail positions in department stores and local malls during the holiday season are a time-tested seasonal job. A large number of restaurants and package delivery services such as FedEx and UPS also typically seek extra help during the busy season such as Christmas.
Retirees with tax and accounting experience could find a slew of jobs during the tax season. If you wish to be self-employed in this field, consider becoming an enrolled agent with the IRS or doing bookkeeping services online.
