As a business owner or ENTREPRENEUR, one of your most important tasks is workforce management. It's your job to make sure you have the right people--and the right number of people--to keep your company running smoothly.
Your employees must work very hard, perhaps too hard and they're letting you know or complaining that they have too much to do. Your task is to determine if they're legitimate. Try talking to your employees and asking them to validate their concerns of being "overworked." Then look at attendance and productivity indicators to substantiate their claims. If what you find confirms their feedback, then you might decide to reorganize and restructure roles and responsibilities to better deal with the workflow.
