2. Benefits do have monetary value, for example the company gym and health insurance means that the employee do not need to pay out of their pocket for these benefits.
3. Health insurance does save money, but not in the way that it is applied to retirement. Furthermore, what if it is not a workplace related incident?
4. This is false. The employer uses money to invest in benefits such as company gyms and cars and such for the use of the employee. Money is not directly given to the employees.
