Many plan sponsors mistakenly believe that they are not required to offer the retirement plan to part-time employees. Regardless of what type of retirement plan you have, all employees, including part-time employees that work 1,000 hours in a year, must be offered the retirement benefit. Though your plan may contain a service requirement that essentially prevents “part-timers” from ever becoming eligible (such as a one year and/or 1,000 hours requirement), part-time employees may NOT categorically be excluded as a class of employees.
