That's the thing, looking at the company they don't work "normal labor" jobs. Infosys is into info tech, consulting, and outsourcing services and looking at their acquisition history I get the impression they buy up smaller companies and consolidate their work into their product. Basically they make websites and tools that your company buys for $100k to analyze and optimize workflow, but the site doesn't work well and they never fix it. After 2 years enough time has passed that the higher ups don't feel embarrassed retiring the software and buying something else. Also, rather than just coding themselves they code with AI or buy other companies that already wrote the code and put it into their own product.

At the end of the day they aren't "working," they are being available. They are the shitty guy who is answering a work call on a Saturday while they are supposed to be watching their kid's ball game. They are the person who has to step out of the movie theater because they are getting an urgent work call at 10 pm on Friday. They are the person who flies back from their vacation two days early because the boss wants to ask about sales numbers. This is how Executive suite types say they work 16 hour days 7 days a week, they count every hour of the day as work because they are available, not because they were being productive that entire time.
