Proper utilization of them will bring huge benefits to your company such as improvement of the work environment and an increase in productivity.

Internal communication is a critical pillar for the success of any organization. Keeping employees well informed and connected promotes a healthy working atmosphere, improves morale, and boosts productivity.

However, you should choose and only use those internal communication tools that are truly useful for the organization. So, what are these channels in a company? We will reveal all the secrets below.

Main types of internal communication channels

The main internal communication channels for large scale businesses cover a variety of tools.

These range from face-to-face meetings to videoconferences, internal chat and others. Each of these channels offers specific benefits.

However, their effectiveness depends largely on careful planning, a clear definition of objectives and topics. We will explain them so you can choose which are yours.

1. Meetings

Without a doubt, we are facing one of the most common internal communication tools. On the one hand, it allows for evaluating performance and evolution of the company or its employees.

On the other hand, it is an ideal space for exchanging ideas, strategies or proposals. A face-to-face meeting requires us to be fully engaged, which offers a greater impact than other communication channels in a company.

It is also true that sometimes they take up time or include more people than necessary. We must determine when they are necessary or not, for which we can follow these guidelines:

Is the meeting necessary? Many times unnecessary meetings are held. They should only be held when it is essential.
The purpose of the meeting: if there is no defined objective, that everyone knows about, it won’t be effective. You have to stay focused on the topic.
Who is attending? For it to be effective, only the essential people should gather. There is no need to have spectators, each attendee can report the outcome to their teams.
Limited duration: Depending on the topic being addressed, a longer or shorter time limit can be established. You must avoid straying from the topic or extending the meeting more than necessary.

2. Videoconferences

When companies work remotely, videoconferences are the best substitute for face-to-face meetings. We will give priority to face-to-face meetings, but if they are not possible we will opt for videoconferencing.

They will be carried out under the same conditions as meetings, again trying to include only the necessary people and with a defined theme and objective.

They save time and shorten distances, and for them to be effective a good connection is also necessary. If it is not possible to maintain a good connectivity, it is better to do without them and look for an alternative.

3. Employee portal

It is a bidirectional channel that improves the efficiency of human resources and helps generate trust in workers.

Employees can access information without resorting to third parties. In the employee portal, they will be able to consult:

Payrolls.
Schedules.
Shift rosters.
Days of available vacations.
And any other relevant information.

It also serves to automate administrative processes or even to manage training processes. It must be accessible and easy to use, in addition to offering transparency and being secure.

4. Employee wall

The employee wall is an internal communication tool used in companies to share announcements, news, and other relevant information exclusively with the employees of the organization.

It works similarly to an internal social network, where employees can access a common virtual space where important messages related to the company are posted, such as:

Policy updates.
Event reminders.
Team accomplishments.
Recognitions.

This type of platform is usually integrated into a human resources management system or internal communication software. Also, it can include functionalities that allow employees to comment, share or interact with the published messages.

5. Internal chat

Another internal communication channel is the internal chat, which has the ability to streamline processes and exchange messages in real time.

They are much more agile than options like email, and they have the advantage of allowing conversations to be organized by topics, projects, etc. A single worker can have multiple chats, both individually and collectively.

For good use, you need to decide which chats are a priority by managing notifications and alerts. Not only do they allow conversations to be maintained, but they also serve to exchange files and make calls or video calls.

It is an internal communication channel essential when working remotely.

6. Email

Although it is losing ground to other internal communication tools like chat, it is still a widely used channel.

In its favor are its familiarity among workers, which greatly facilitates its use. This is the first step for it to be an efficient internal communication channel.

However, its use must be regulated, avoiding endless email chains. Tools like chat can replace it, but it’s still the best way to share files, links or important information like the date and time of a meeting.

7. Phone

As the years go by, the telephone continues to be one of the most used corporate internal communication channels. It allows maintaining connectivity between work teams, both those who work in person and those who work remotely.

With the development of smartphones, it has gained importance as an internal communication tool thanks to apps like WhatsApp. In fact, it is even possible to “clock in” at work with a mobile through this application.

Its main disadvantage is the invasion of the personal lives of the employees. That’s why it’s important to set a schedule for its use, avoiding disturbing those who are not working.

8. Corporate social networks

Although their full potential is not always exploited, they allow a flexible, continuous and immediate exchange of information.

In a collaborative work environment, they offer a safe space to converse, share knowledge and opportunities in real time or to expand professional networks.

We should not overuse them, but they can boost group dynamics and the sense of belonging.

Other examples of communication channels in a company

The use of magazines, blogs or podcasts serves to transmit corporate news and other topics of interest to employees. However, these are generally unilateral channels.

On the other hand, holding corporate events promotes relationships between coworkers.

Additionally, you should have a whistleblower channel for companies, which offers employees the opportunity to report irregularities.

Anonymity will be key to its success, as it allows employees greater freedom when communicating with the company’s management.

In addition to the channels mentioned, there are other means that could be used to improve internal communication within a company:

Internal blogs: An internal blog can be a platform where business leaders share ideas, updates and reflections on the direction of the organization.
Discussion forums: The forums allow employees to discuss relevant topics, ask questions and share knowledge in a structured and accessible manner.
Mobile applications: Corporate mobile apps facilitate access to information and communication from anywhere, especially useful for roaming employees.
Surveys and polls: Polls and survey tools help gather feedback from employees on various topics, promoting a two-way communication.
Events and Team Building activities: Organizing events and activities encourages interaction between employees from different departments, strengthening relationships and improving team cohesion.
