Your employees will need to check with the state to see whether they even qualify for seasonal unemployment. Last I knew, there are 10+ states that have closed the ability to collect for anticipated seasonal unemployment, usually based on time-frame or industry. For some states, landscaping is exempt from the seasonal classification. Essentially, for recurring, seasonal unemployment scenarios, the employees knew what they were getting into when they took the job, so that gap in employment is now on them.
