The labor market is very tight right now, and it is understandable that you might have questions about how to get people hired for your lawn care services. What you need to remember about this is that you can offer them something that other jobs cannot. You can offer them near-instant money.
Most lawn care services operate as a cash or check business. Thus, it is easy to pay your employees at the end of their shift instead of at the end of the week. Many workers need money as quickly as they can get their hands on it these days, and that means that it is to your advantage to make sure you push these opportunities out to people as soon as possible.
Think about the labor situation as it is right now, and you might decide that you need to leverage all that you possibly can out of the type of work that you offer. One advantage that you can provide is that instant cash.
Advertise these positions to those who might need that kind of work. Put out advertisements to people who might be interested in getting this kind of work right from the start. This is why you need to do what you can to put those ads where people will see them. Put them online, but also put them in your local area where people visit.
