There are several synonyms that can be used in place of "more hiring" depending on the context. Some common options include recruitment, staffing, employment, and hiring spree. Recruitment often implies a more formal process of attracting candidates to fill specific job openings, while staffing and employment are more general terms used to describe the overall level of hiring within a company or industry. Hiring spree is a more informal term that suggests a sudden surge in recruitment activity. Ultimately, the best synonym to use will depend on the tone and focus of the message being conveyed.
