Wyoming allows employers to adopt different vacation policies. For example, an employer can create a company policy that says you have to use your vacation days earned within that year - so if you earn vacation days in the year 2020, you have to use them by the end of the 2020. However, if a policy doesn't allow you to carry over your vacation days to the next year, your employer has to give you an opportunity to use them or issue compensation for them. In Wyoming, vacation days are typically only earned once you have worked with the company for a specific time frame, usually one year.
