I wouldn't
JCP - see below
I don't think letting a room is crossing a line, nor do I think line management is, though like you say, there may be times where you do things/refuse stuff that are shit. I also don't think that saying worse people would do it if you didn't is a good argument. It's about your relationship to capital, and whether you are, as part of your job, seeking to create/ensure the maximum extraction of surplus value from your (company's) staff. Being a good manager, likewise being a good landlord, doesn't change that relationship.
I should have said JCP staff, management too (even more so tbf), not just advisors. I said JCP intentionally though, not DWP, DWP does far, far more stuff than just the JCP. I'd bracket people who work on ESA tests here too though, and I'd guess DLA/PIP tests too, but it's JCP that I personally know.
JCP used to be about helping people find jobs. Now it's about sanctioning them, pushing them off benefits, stopping them from getting the money they need to eat and stuff. I know JCP staff too, good ones, who help us when we have a sanction we need to appeal or when they have info that'll be useful to us, and they are all on disciplinary action because they're not sanctioning people. They'll be sacked or will leave sooner or later, and they will be replaced with people who are happy to sanction, to take the food off the plates of claimants. In case anyone asks, yes I've told them what I think to their face, (I've talked at a public meeting on a strike day where it was mostly PCS staff and said what I think the JCP is becoming, this was 2 or 3 years ago now, so I wasn't as forceful, warning of the future to come, which we're further into now), we work together because there are more important things, and because I don't think they're scum for being there, I just think they should leave.
My experience, both first and second hand, is that the majority, and an increasing majority, are not fair or caring. They have a workload that prevents this because they have too much to do, and the culture being put in place (which I think started when JSA was introduced in 1994 but has gone off the scale with this government) is one in which it is believed that taking away the money people need to live is doing them a favour, a good thing, they deserve it - and it's increasingly believed and bought into by JCP staff. Targets for sanctions ffs, jobcentre near me gave easter eggs as a reward to the staff who sanctioned the most people a couple of years back.
The stories I've heard or read about why people are sanctioned and that doesn't include all the ones which I heard in person and helped get overturned.
The bad ones pick on people with poor language skills, mental health problems, anything that means that they know they won't challenge it. They chase their targets dilligently and look for every opportunity to sanction someone, no matter how stupid the reason is, setup increasingly complex and stupid demands on claimants and try to trip them up. Maximum sanction length is now 3 years. No money for 3 years because your JCP manager needs to get another sanction to meet their targets or be put on disciplinary action.
Anybody who works as a JCP advisor does so knowing that they will either have to stop the money people need to eat, or they will have to leave the job (and ultimately they'll get sacked even if they don't choose to leave and refuse to sanction people).
Police can kill us, beat us up, lock us up. Screws can keep us locked up. Bailiffs can take away our stuff. JCP advisers can take away our food, warmth and clothing and force people to work for free. And they all do those things, every single day. Well, the JCP advisors don't, christmas, weekends and that, but every working day they do, thousands of people.
I think the comparison is fair. JCP is still transitioning though, so there's still that part of it that they are gradually pushing out. That is the past. This shit, these attacks, the violence and misery - that is the future.
