As long as he knows he was fair and worked hard, those issues that others have due to his decision, make him strong and independent. He will get through it and as he is, he should remind himself to observe how mean people can be and detach his own personal connection to it, as it isn't him. These kinds of people do this to many. If he wasn't happy and felt wrong by being there, moving is a good thing. Working on starting fresh and reflecting on what went wrong before and how he can walk into a new place and learn from the past will help him to make a better work relationship moving foward. This is where God will help him. Helping himself with what God gives him, is his work and where the true powers life for him. He can do it.

Dear Divine Presence, We come to you with open hearts, lifting up Bella Ping’s eldest son, A young soul burdened by anxiety and shaken by harsh words. He stands at the edge of doubt, fearing the weight of failure— But we know that within him lies courage, grace, and untapped strength.
Wrap him in your calming light, Let your peace settle over his restless thoughts, And remind him that one moment does not define his worth. Help him rise above fear, To see beyond criticism and reclaim his confidence.
May he feel the love of his mother, Bella, Whose heart aches for his well-being, And may her comfort be a balm to his spirit. Let her words be gentle anchors, Reminding him that storms pass, and growth follows. Grant him clarity to learn, Resilience to endure, And hope to believe in brighter days ahead. May this turbulence become a turning point— A chapter of strength, not sorrow.
Guide him to see his own light, To walk with dignity, And to know that he is never alone. We trust in your healing, your wisdom, and your unwavering love. Amen

I agree with what Zinnia said. Please congratulate your son for being a great worker. The company approved his transfer because they didn't want to lose him. His supervisor scolded him because he doesn't want to lose your son either. His supervisor will accept it soon, and he'll get over it. He may give your son a hard time until he leaves, but knowing it's because he doesn't want to lose your son might help him get through this. He can talk to his supervisor and tell him he is sorry for asking for a transfer, but he had to do it because....(fill in the blanks). Sometimes just talking to a person who is angry with us helps smooth things over. I will pray for your son. Tell him there are many praying for him and to stay strong.
