Why does China Airlines often recruit people?

It's not just China Airlines that often recruits employees. Many companies are like this now. The reasons are as follows: First, the company's business has developed rapidly and the company has expanded in an all-round way. Due to the shortage of manpower, it is really necessary to recruit frequently. Second, as a long-term recruited talent, it takes time for beginners to get started, especially for technical classes, and it takes a long time to train to adapt to the post and create value. The third old employee is stagnant, unable to create better benefits, and needs to be dismissed, but not in large quantities. Therefore, long-term recruitment and selection of suitable new employees will bring new energy. Fourth, the current employees are highly mobile and constantly change jobs, so they can only recruit supplementary personnel. Fifth, the role of advertising, the general large-scale recruitment platform, when you use the search engine, you can find the information of the unit by looking for relevant keywords, which plays the role of advertising invisibly, and the cost is not high, not only can you complete the recruitment, but also can include the advertising function.
