Most people work a set schedule every day, for example, 9am -5pm, or 3pm-11pm, etc. With a flexible schedule, your hours are not as rigid (hence the term "flexible"). There are different types of flexible schedules. You may be allowed to work from home on certain days. Or maybe you are in school and have classes on certain days. Your employer allows you to work 7am-3pm on the days you have classes and 9am-5pm on the other days. Some employers allow you to pick your hours within a certain time frame. For example, you must work 8 hours a day, but those hours can be anytime between 7am - 6pm. The hours you work can vary day-to-day, as long as you work 8 hours daily. Employees obviously like this flexibility, and employers find that it leads to greater job satisfaction, fewer sick days taken, and less job turnover.

I have flexible hours. I can teach you ANYTIME on Monday.

It means a schedule that allows an employee to work hours different from normal company times e.g 8am-5pm. So if you work 2hrs a day or mornings only or afternoons or some days a week, you have a flexible schedule or hours.

"Flexible hours" means having a schedule that you are willing to change. It is the opposite of "fixed hours." So for example, if a professional has "flexible hours," he or she is willing to work at different hours one day compared to the next. The person might say, "I generally work from 9am - 5pm, but I have flexible hours." This means, you might be able to see that person at 5:30pm if you suggest it because they are willing to change their schedule.

Flexible working hours refers to the schedule which allows employees to start and finish their workday when they want. This means that employees can come to work earlier or later than the set time. Link = https://www.talentlyft.com/en/resources/what-is-flexible-working-hours
