There is no general requirement in Wyoming that sets how often wages must be paid. Every firm, person, or corporation engaged in the operation of any railroad, mine, or refinery; work incidental to prospecting for or the production of oil and gas; and any factory, mill, or workshop must pay its employees no later than the 1st day of the month all wages earned up to the 15th day of the preceding month, and on the 15th day of the month all wages earned from the 16th to the last day of the preceding month (WY Stat. Sec. 27-4-101).
Any employee absent from work on such regular paydays must be paid upon demand at any time thereafter. If the 1st or 15th day of any month falls on a nonworkday, all employees must be paid on the preceding workday. These provisions do not apply to agricultural operations.
County employees are to be paid an annual salary in equal monthly installments. State employees are also to be paid monthly, no later than the 8th day of each month.
