Human resources outsourcing is the involvement of third parties in the management of talent at a company. This means that the company either does not have its own HR department or HR officers, or in other situations they perform only internal management and recruiting activities, but outsource HR specialists take the responsibility for planning, developing and scaling HR in the company. 

Sometimes hiring third parties for HR outsourcing is necessary if the company is experiencing high levels of burnout, stress, or other problems among the team, and it becomes necessary to look at the situation from the outside and provide qualified and unbiased assistance, or help with decision-making regarding specialists. In this case, an external HR expert acts as a moderator or auditor to resolve the discussion or to join the assessment of employee performance, engagement, or potential development.
