S4 provides flexible benefit choices designed to suit employees' needs and the needs of their families. Each employee assumes the responsibility for making important decisions regarding his or her personal well-being.

Fully Funded Retirement Plan

S4 contributes a percentage of the gross salary into the employee’s Retirement Plan.

Employees direct the plan contributions into the mutual funds that best suit their individual investment goals.

Employees accrue 20 days of paid time off per year. These amounts increase at milestones of employment.


Our employees receive 10 paid holidays, which correspond to the 10 federal holidays. We offer four (4) of these holidays (Martin Luther King, Jr.’s Birthday, Presidents' Day, Columbus Day and Veterans' Day) as “floater” holidays. When our clients’ contract terms permit, employees may work a “floater” holiday and then claim that holiday by taking time off at a later date.
