When firms promote products to their own employees as part of an internal marketing effort, they are using a

pushing approach

Explanation: Push marketing refers to a sales technique in which corporations try to bring their products and services to consumers. The word push comes from the belief that advertisers are trying to push buyers towards their goods.

Common marketing tactics involve attempting to sell goods to directly to customers through corporation dealerships and bargaining with vendors to sell their goods to them, or setting up point-of-sale exhibits. To return for this greater visibility, these merchants may sometimes receive extra selling rewards.

Thus, from the above we can conclude that the correct answer is pushing strategy.
