I don't know why I have hired several people in my current position and asked for help, but I am always restless and don't know what to do.

Well, it depends. If your task is heavy and time is tight, one person can't finish it on time, which will affect the company's task. It is certain that the company recruits employees to let you cooperate with each other and complete the tasks stipulated by the company as soon as possible! As for your thinking that the company will fire you, it's completely unfounded. As soon as you sign the labor contract, the company can't fire people casually for no reason. This is against the law and will compensate you and miss the contract. Secondly, if you should be fired, you probably won't renew your contract when it expires, which will also compensate you for unemployment benefits. Anyway, the company won't do anything thankless! Work with peace of mind unless you think twice before you act. I don't want to continue this job!
