possible case against staff

Hi, I have a problem with people management and my staff is somehow taking advantage of this. As a background, he is tasked to work on the general maintenance of our office and be a messenger. He started 2 years ahead of me and is 5 or 8 years older than I am (irrelevant, i know). And for the longest time..

1. he would often resort to doing what is asked from him just when feels like doing it,
2. he refuse to accept some errands saying "natatakot sya" in the place where he is tasked to go (and would insist to have the janitor do it instead of him)
3. he does not reply to urgent messages even if he has a company issued phone (which he uses more often for his personal calls/texts)
4. he often walks out, raises his voice, or talks back when I have him do something- probably just to end the conversation
5. he confirms first with our manager (the one i report to) whenever I ask him to do something before he does it (he's quite close to the manager)
6. he does not follow office protocol when it comes to accepting messenger errands
7. he talks back to some managers, co-employees, contractors, security personnel (in short, he's plainly mahilig magmagaling and bastos)
..and the list would seriously just go on and on.

anyway, point is- what possible reason can I "charge" against him? I never wrote a single memo for all his shortcomings but his actions are too much. He's like a bully that you just want to get rid off.

thanks!

Item 1,2,3; just be sure to give him letter/memo and ask for his explanation. you don't have to do it yourself, just instruct HR (its their job). tell HR that he messenger violated items 1,2,3 of the labor code. sila na bahala jan.
