If one wants to give credit to the most profitable and biggest American corporations, then probably their most notable calling card is frankly that they are immensely skilled at the making of money, above all. For instance, a given company, might initially believe that a directly employed workforce, with a fair benefit package and a living wage, would logically thereby create workforce stability along with labor satisfaction, and hence would be the best way to assure profitably and consistency; in addition to demonstrating that this corporation has make it a point of being of material usefulness and of benefit to that community that it is an integral part of. That, though, is not what most large corporations actually do in the present day, as instead they prefer to see every aspect of their business as something that needs to be carefully investigated and analyzed, for the sole benefit for that corporation, in order to primarily increase profitability.
This so indicates that corporations are first and foremost, cognizant that a direct employee, so subject to benefits such as vacation time, sick leave, personal time, maternity leave, healthcare, holidays, bonuses, and the employment payment matching of social security and Medicare taxes means that the wage so being paid to a given employee, is far higher than their payrate. So then, corporations have a very strong tendency to look upon who is so employed, and therefore make a conscious determination as to whether or not, certain current direct employees, could conceivably be replaced by temporary employees, or their work subcontracted out to agencies, or simply outsourced to somewhere else, such as a foreign country, of that work so being presently performed in-house. In other words, a conscientious company that cares about little more than their bottom line, is going to have a very strong inclination to look at every aspect of their company and thereby determine as to whether or not, that company needs to directly employ those so currently working in their employment, or whether that work could be successfully done by a temp, an agency, or outsourced, at a lower cost point, with subsequently less financial exposure and liability to the company.
In other words, when corporations, care primarily about profitability above people, and clearly care about the making of that money, over and above responsible obligations that they should have to their community as well as to their country, then they are going to have a strong tendency to make decisions that benefit their bottom line, above all else. In an era, in which unions have become marginalized in virtually every aspect of the private sector, and of which the government has apparently ceded its influence and power to those corporations to do what they so may, then this so signifies that the private sector knows for a certainty that when it comes to negotiating with employees, temps, agencies, or the outsourcing of work, that those corporations have not only a lot of viable options, but that such negotiations are going to overwhelmingly favor the employer over any other entity.
So then, it really comes down to the salient fact, that many corporations, take absolutely zero pride, in the sheer number of direct employees that they so have engaged, but actually prefer to be measured by the total number of sales or profits that they have per employee, and therefore make it their principle point to increase such at the expense of being fair to their society and especially to the good people that make up that society.
