How to tell the boss if I don’t want to take leave on my return trip on May 14th?

The suggestions for you are as follows:

1. You can discuss with your leader whether you can work remotely on the 4th, or make up for the shift earlier or later. You need to show that you value and take responsibility for your work and will not affect the progress and quality of your work. You should make work arrangements in advance and handle all matters that may require handover or coordination to avoid causing trouble to your leaders and colleagues.

2. Tell your leader in advance that you have some urgent personal or family matters to deal with and will not be able to come back to work on the 4th. I hope he can understand and support you. You should try your best to talk about specific things, such as attending the wedding of relatives and friends, taking your children to the hospital, handling house repairs, etc., so that the leader can feel your sincerity and difficulties.

Note that you can express to your leader that you are grateful for his trust and support in you and that you respect his decision. If he agrees to your request, express gratitude and commitment; if he rejects your request, express understanding and compliance. Regardless of the outcome, you must maintain good professionalism and attitude.
