Any area that has a workload to handle a full time employee all year around.

It really is simple.

If the workload requires a full timer, hire a full timer.

For example you might need 2 forklift drivers full time all year around.

During Christmas time you might need 7 forklift drivers.

This is just an example. So you would hire 2 full time good workers. Then hit up recruitment companies or any resource to get the people for Christmas.
