Know how to present your self if you are asking for more hours at work. If you are able to focus on your strengths and what you can do for your company, it will be easier to convince them to give you more work hours. Be punctual and look for staff to take over if you're not available.
Asking for more hours at work
Before asking for more hours, you need to know what your manager's expectations are. A manager expects his or her employees be reliable and productive. Managers expect employees to be dedicated to the company and work hard. It is important to show enthusiasm and be on time. You must be prepared to work overtime or weekends, if needed.
When asking for more hours at work, you should do so politely and in a civil manner. Don't put your co-workers on defense. The best time to ask is when things are going well. How you speak can impact the outcome of whether you are granted extra time.

Being on time
One of the most overlooked aspects of time management is showing up on time. Many people fail to be on-time because they don't know when they should show up at work or leave at a specific time. As a result, they work on whatever comes up and don't schedule time for important work. They still have a lot of work to do when they leave the office around 5 pm. Instead, choose a time each morning that you want to leave. Block it off on your calendar. Then, set an alarm on the phone. This will make it easier to commit psychologically to leaving work on schedule.
Find staff to cover the shifts that you don't wish to work
It's possible to find staff willing to help if you don’t have the time or someone to fill in for you. It's important that you find someone who works around your schedule. Don't just find someone who has volunteered to cover before - make sure they'll keep their word.
A chart of availability can help determine who is available and avoid you calling on employees who may not be interested in the shift. An example: You wouldn't ask an employee who only works open shifts to work on Tuesday. It's also a good idea to define a specific time period during which employees should notify managers about last-minute cancellations.
Communicating your request
To make your request a success, communication with your manager is crucial. Approaching your manager should be courteous and respectful. Please explain the reason behind your request. Also, state the benefits you would like to receive. Share solutions that you have developed in your work and how they will benefit the company. These ideas can be used by the manager to justify giving you additional hours.

You need to know the expectations of your boss before asking for an increase in working hours. You should state that you are not requesting additional hours for a specific time and not urgent. Be sure to include examples and a backup plan for dealing with obstacles.
