Dear [Supervisor/Manager], I am writing to request the cancellation of my leave of absence, which was previously approved for the period [start date] to [end date]. Due to unforeseen circumstances, my availability has changed, and I am now able to continue working during that time. I understand that this cancellation may inconvenience the team, and I sincerely apologize for any inconvenience caused. However, I assure you that I am fully committed to fulfilling my responsibilities and contributing to the success of the company. During the period initially approved for my leave, I had intended to take time off to attend a family event. However, the circumstances of the event have changed, and it is no longer necessary for me to be absent. I recognize the importance of my presence at work during this time and am more than willing to adjust my plans to accommodate business needs. I am eager to resume my duties and contribute to the team's goals. Furthermore, I am confident that my dedication and work ethic will remain strong throughout this period, despite the initial leave request. Please consider this letter as my formal request for the cancellation of my leave of absence, effective immediately. I am prepared to take on any necessary catch-up work or additional responsibilities to ensure a smooth transition and minimal disruption to the team. I understand that final approval is at the discretion of management, and I would be grateful if you could consider my request promptly. If there are any further details or discussions required, I am available at your earliest convenience. Thank you for your understanding and consideration. I am looking forward to resuming my duties and continuing my contributions to the success of the company. Sincerely, [Your Name] [Contact Information: Phone number/email]
