I'd feel massively conflicted about it. Definitely guilty. Not sure I'd want to do a job that totally bulldozes other people's autonomy. Even if it's supposed to be for their own good. I'd feel like such a hypocrite too. Of course- it would depend on whether they called ems themselves. Obviously, if they called then- that's something else.
I don't really like hypocrisy/ lying/ towing the company line in any job to be honest. I'd struggle even to teach in my specialist subject because, I coudln't genuinely fill them with optimism about finding a job/ having a successful career- when I know how hard it is. I think a lot of jobs are probably dishonest in some way.
