How to implicitly urge others to hurry up in life?

Don't be embarrassed, just push it again and again. Send a text message first, make a phone call without any action, dial the landline first, and then dial the mobile phone if you can't find anyone. If this is an open office with a straight line of sight, just call him and never stop until you reach your goal.

I'm sure your boss will not blame you. Although you are annoying, even your boss will be elated at the thought that you are working hard. Nothing is more satisfying than the competent staff and everyone doing things in an orderly way.

The boss knows all the important things, so there is no need to rush them. He will work then. He is more anxious than you.
