1. When I go for a bike ride, I take my phone with me. I don't want to also take a garage door opener.
2. My neighbor calls me up at work and says he wants to borrow my chain saw. I remotely open the garage so he can get it.
To be clear, I don't want this. I wouldn't trust it. But there are legitimate use cases.
And no, stuff like this doesn't need to be mentioned during the job interview. (A company wouldn't want to know it, anyways, because it increases the risk of a discrimination lawsuit.)
And chances are, at his position, even though he's probably have to be in the office, he'd very likely not have to work overtime (government contractor and all).
So it's not only a temporary situation, but one that's very unlikely to happen over the two months.
And the supervisor was probably correct - it didn't matter to him and being human was the best thing possible. I've had to tell coworkers to simply go home or to not worry about things when they needed to take care of someone. Granted, I don't have the authority to do so, but I will defend my decision as a decent human being trying to be compassionate. There is no work so important that it cannot wait until the next day that cannot be temporarily handled by someone else that would justify lack of compassion.
Again, all we have here is one side of the story and I do not take it 100% at face value. I did not suggest that he would need to say his wife is sick, but if the job was described as "be here when we need you, which may be after hours from time to time" then that's the job. If he had worked there for a year and this came up, then he would have cause of action under FMLA. But if you accept a new job knowing that you are going to be a couple of months before you can meet all needs, you should be up front about that.
BTW, this may sound worse than I mean it, but saying "...very likely not have to work overtime (government contractor and all)" shows a complete lack of understanding of the industry.
Of course it's technically feasible. It's called universally agreed upon standards and conventions.
I think you are confusing the word "feasible" with "possible"
