 Employers have a 30-day period between registration and implementation to notify employees who can then opt in, alter, or opt out of the program. Workers in the U.S. are about 15 times more likely to save for retirement when their workplace has a savings plan, according to AARP research. That jumps to 20 times more likely when the contributions are automatic. Delaware employers have until October 15th to register for the program or certify they are exempt.
