Week One, 100 level first year Business Intro class at every college and university in the United States. Gather round the campfire, sing along everyone -
".. a fiduciary responsibility to maximize shareholder profits/shareholder value."
Public traded corporations, as people, are sociopathic. Failure to maximize profits is malfeasance. Employees exist as resources to be managed.
IT exists as a cost center within most corporations. It doesn't earn money - it's a money sink. It's viewed as a necessary evil by the bean counters to keep the the gears turning - To keep Outlook strangling your will to live with 100 unread emails as you unlock your $600 Dell workstation every morning, Powerpoint decks carefully crafted to optimally dispirit you in hourlong lunch meetings where the leveraged synergy tumbling out of the projector could have been reduced to 10 bullet points on a post-it note - or an email.
IT managers and middle don't have much to "win" with. Meeting project deadlines, otherwise the job is to simply maintain the status quo. Keep the machinery humming. When you do your job well, you're invisible. Invisible doesn't get promoted. The Sales & Marketing guys have numbers to brag over. Those numbers directly translate to dollars in the company's pocket.
Some mid to upper level Disney technology officer wanted something to brag about. They took a fleeting glance at Disney's operations and decided that their (presumably) top quality, experienced IT people could be replaced with H1B robots earning half the salary. H1B robots have a legal minimum salary that's frequently half that of their American counterparts. H1B robots legal status in the U.S. is directly tied to their visa; losing the visa puts them out of status and in violation of federal law. This creates a system where the corporation has enormous and undue influence over the H1B workers' job. Be model employees - or else. Work 60 hour weeks. Come in Saturdays. Do the shit work no one else wants to touch. Do it with a smile. Do it with a smile for less than half the salary your predecessor earned, or we can terminate you on a whim, throwing you out of status, forcing you to leave the country at penalty of US law.
What a dream for employers. Half the pay, and the crushing weight of the US Department of Citizenship and Immigration Services and Department of Homeland Security constantly on your mind as you're at the office at 7:15 yet another evening at your 8-5 job.
