R.I. Gen. Laws § 28-14-2
Every employer shall establish a regular payday on which wages shall be paid in full in lawful money of the United States, or checks on banks convertible into cash on demand at full face value. Each employee must be notified in writing, or by posted notice that may readily be seen by all employees, of a change in the scheduled payday at least three (3) paydays in advance of a scheduled change. Each scheduled payday shall fall within nine (9) days of the end of the payroll period for which wages are computed unless prevented by inevitable casualty; provided, that if the ninth (9th) day is a holiday, payment upon the next business day shall be deemed a compliance with the terms of this section; and provided, further, that if at any time of payment any employee is absent from his or her place of labor, he or she shall be entitled to payment on demand at any time thereafter.
