A staffing agency, on the other hand, acts as an intermediary between employers and job seekers. They assist companies in finding qualified candidates for temporary, contract, or permanent positions. Staffing agencies typically handle the recruitment, screening, and initial selection process for the employer.

Both direct hire and permanent hire can be facilitated through a staffing agency. In such cases, the staffing agency serves as a resource for identifying and vetting potential candidates for permanent positions, and once selected, the candidate is employed directly by the hiring company.

When writing a resignation due to health issues, it's important to be clear, concise, and professional. Start by addressing your employer and stating your intention to resign. Briefly explain your health situation without going into excessive detail, expressing your regret at having to leave the position. Offer to assist with the transition by providing a reasonable notice period. Express gratitude for the opportunities and support you've received during your time with the company. Close the letter with a professional and courteous tone. Remember to keep the letter short and to the point while maintaining a respectful and appreciative tone.
