Are you searching for software to manage your employee work schedule? Well, I just read an article that evaluated several free scheduling software programs.

Remember, scheduling software programs won't create schedules for you. You have to have a pattern already in mind. Sure, there are free templates to use, but are they a good choice? Just because a pattern has the shift length and format (fixed vs. rotating shifts) you want doesn't mean it's a good approach for your group. You want a schedule that does three things: (1) optimizes coverage, (2) minimizes costs, and (3) maximizes employee satisfaction.
