In an enterprise, no two employees have jobs of the same difficulty and no two of them take the same salary. Every employee made the following two claims:

1. Less than $12$ employees have a more difficult job.
2. At least $30$ employees receive a higher salary.

Assuming that an employee either always lies or always tells the truth, determine how many employees are there in the enterprise.

Let's think step by step and output the final answer within \boxed{}.
