Flextime is a tool that can be adopted by workplaces to allow employees a more flexible, and accommodative schedule. There are various ways in which flextime can be incorporated into a workplace such as allowing for variable hours or extending workdays to allow for a shorter work week. Flextime allows employees to adjust their time for personal needs, which can lead to a happier, healthier, and more productive workforce. However, many businesses have specific hours of operation, and are not able to accommodate this type of scheduling.
