How can I help new employees settle in?

I manage a mid-level firm that recruits new staff time and again. We do not have a HR department as yet. Therefore, as the manager, how can I make new employees easily settle?

At the workplace, it is necessary that new employees know their environment as they try to fit in.
This can be done through orientation programmes that help new staff to know their respective jobs, departments and reporting lines.
Orientation serves as a roadmap, providing an understanding of the company’s general framework.
A company can have a systematic method of orienting staff. Informally, new entrants get orientation from co-workers. The danger with this approach is that some co-workers can give misleading information.
Orientation is vital because it helps to inform individuals’ scheme of work and create the maps the new staff will have regarding the company.
As the old adage; ‘first impressions are lasting impressions,’ an effective orientation has an immediate and lasting impact on a new employee and can make the difference between their success or failure.
While conducting the orientation it is important to address key issues such as history of the company, strategic plan, overall financial background, policies, marketing and growth plans, job responsibilities, and administration procedures.
While some firms have overall orientation programmes which are designed for all employees, others develop specific programmes for one type of job classification or one unit.
The length of the orientation varies. It can be two or more weeks.
Every employee should be given an orientation packet of information that includes company’s chart, copy of policies, benefits and procedures.
