Back before companies had automated phone systems, they either had to hire enough people to answer phone calls or customers would get busy signals most of the time. Getting busy signals all the time meant losing business, so companies generally maintained enough employees to answer calls. You'd sometimes get a busy signal, but most of the time a real person answered your call right away. Now, they let the machines answer the phone and leave you on hold for long periods of time. This is a pretty good indication pf what corporations really think about their customers. Not only do they have too few people to answer the phones, but they hire low-paid people in poor countries to answer calls. Sometimes it's difficult to understand the person who answers the phone because English is not their first language. (There's nothing wrong with English not being your first language, but employees who can't speak clear English are not the right people to assign to speaking to customers who speak English.) Then while you're waiting on hold to speak to a low-paid employee in India, you have to listen to pre-recorded messages suggesting they'd rather you not speak to one of their low-paid employees, but would prefer that you used their web site so they could lay-off one of their low-paid employees. And then the pre-recorded messages have the gall to tell you that your call is important to them and you are a valued customer.
The corporation probably calls the department that does this "Customer Service" - because they want to give the illusion they care about their customers and are trying to serve them.
How do corporations view their employees in general? Well, the department that handles employees is rarely called "Employee Services". They're not even trying to maintain an illusion there. Often the department is called "Human Resources". That is, employees are corporate "resources", like equipment and materials needed to do business. A corporation's inanimate resources don't ask for raises, get married and change their names, add children to their health insurance, or have disputes with supervisors. Handling their living "resources" can require doing some things you don't have to do with office furniture, machines and raw materials, so there's a separate department - but they view people as items. Even disposable items that lose their jobs and health insurance when the company's executives make stupid decisions that cause the company to lose money.
The purpose of a corporation is to make money for its owners. That means the company has to receive income. The people who give the company money are called customers. "Customers" may not give that money if they're not fooled into thinking the company cares. Even then, "customers" aren't giving charitable donations to the company - they only give the money in exchange for goods and services. In order to have goods and services to sell, the company needs employees to produce them. From the corporation's point of view, employees are nothing more than a means to get that money. The employees are "only" doing what is needed to provide customers with something for which they're willing to give the money to the company. As essential as this makes employees, corporations don't consider them inherently worth rewarding any more than they'd give a reward to the iron ore they use to make steel.
From a non-business point of view, companies are nothing more than middlemen between you working to produce goods and services, and you getting the goods and services you earned by working. Working people are the under-appreciated producers that make customers possible and they are the customers for most things. Somehow, it's businesspeople who aren't personally making the goods and services - who give only an illusion of "customer services" and don't even pretend to be trying to serve their employees - that end up with most of the wealth.
Are you a "resource" or a person who works hours every day to provide the country with the necessities and comforts of life?
