Powerplay in the work place

Dear members

I am currently having problems with a trainee where I work.
I had asked this person to do something very benign for the job not for me personaly.
He told me I had asked too much of him,refusing to help me.

Afterwards he went to complain about me to my boss.The bosd told him
he had to cooperate and do what I asked.Thinks he is taking liberties etc this person having shoot themselves bit in foot.

Now he is trying to tell me how to do things and questions what I do.
I have defended myself but find it all very stupid

I am usually too nice to people too friendly.
I am trying to change certain behaviours.
Does anyone have any good ideas?

So I asked
Should I be defensive?
Got hexagram 19.1

Which suggests an approach.So no I should approach and not be too late in doing so.

I asked Give me some advise please on how to deal with N?
I got hexagram 5 4 and 5.

I must get out of pit or blood.Not engage with this man?
He is moving to a different department soon.
Eat and drink don't worry too much.I have other good things going on.??

Or give him something to eat as he is likes to eat a lot keep him happy can't be that no.

Thanks I do try to always update.
So if anyone has an idea?

I don't tend to comment on other peoples readings as
still learning but have done if I had very important experience.
