That is an interesting point to bring up. Within my current company, I have seen how teams are not allowed bring in more individuals even though the workload has increased. And it is unfortunate because it puts more burden on the current employee. To solve this current issue, the company tends to hire more contractors rather than employees through company based on necessary projects requirements. So once the project is completed and the team is required to be reduced, it is easier to terminate the 1-year or 2-year contract and can have the option to renew the contract if necessary. This allows the company to outsource the resources for the projects and maintain the flexibility to add or remove depending on the budget requirements.
