1. Communicate directly with the leader: You can tell the leader that you didn't attend the training and ask if it is possible to arrange another time or way for you to attend.
2. Provide alternatives: If you can't attend the training arrangement of the leader, you can propose other alternatives, such as attending other training courses or online learning.
3. Emphasize your work experience: If you have enough work experience, you can show the leader that you don't need to attend training and promise to continue to work hard to improve your skills and abilities.
4. Put forward your ideas: If you have better suggestions or opinions on training, you can express to the leaders that you want to participate in training planning, so as to better help the development of the enterprise.
The most important thing is to maintain a positive and polite attitude and avoid excessive quarreling or sticking to one's own opinions. I hope the above suggestions will help you.
