I can’t speak to the piece about getting paid for phone calls, but I do know that when people are out on medical or maternity leave you’re supposed to leave them alone, and they you, even if it’s just a quick question. I’ve seen coworkers shut down in emailing things like “where do we send the whatevers?” and I had a client out on medical leave for cancer who couldn’t contact work and felt tortured by the three month disconnection. Social interactions yes, work business no. I assume there’s a legal basis - is there an actual fee-for-service obligation? I don’t know, but I do know that “they don’t work here” and so “why are you contacting them” make sense without any whiff of collusion.
Have you asked the demoted guy what he did? Seems a lot easier than sleuthing around trying to dig it up and “establish a pattern.” Maybe he screwed up a big account or project. Maybe he screwed the wrong coworker. He is the one to ask.
If that seems like an awkward conversation to have, it’s because it IS awkward to chase this down, and I would personally not do it. If you like your workplace and your job, leave it alone. If the snake in the grass shit-talks someone to you, tell her you prefer not to speak of others unless they’re present or else respond vaguely and then walk away. I tend to go with a vague frown and noncommittal “oh wow” or some such, and then move away. If you discover she’s shit-talking you, go ahead and get curious.
A manager I liked very much recently got fired at my office. I thought she was competent, hard working, and kind. But the nurses, who eat people alive (this was the 5th practice mgr in less than five years) didn’t like her, and the clerical staff blamed her for organization-wide changes (rapid growth has forced a big push for productivity, we’re paying for expansion). People were celebrating when word got out. I thought it was sad and unfair, so after thinking about it for a bit - wise or unwise? morally obligated or not morally obligated? - I found her on Facebook and said something along the lines of “I just wanted to reach out to let you know that I was sorry to hear you were gone. I enjoyed working with you and appreciated your hard work and dedication. I hope whatever comes next is rewarding.” She wrote back politely, with a “keep in touch!” which I will not do. I requested and received no specifics - she even noted in her three sentence response that she wishes our organization well, a nicely diplomatic move on her part. I assume she was screwed over, but it is not my pattern to establish and the last thing I want is HR’s negative attention. I also know that there’s a possibility that she did something wrong - did something sketchy with protected medical information, or money or whatever.
I like my work and am well supported in doing it by my organization, and although I don’t always love the culture of my workplace, I like most of the people there as individuals. Had the fired manager tried to discuss the specifics I would have shut the conversation down with an “I’m not comfortable.” But on the other hand, had I viewed her as someone who would drag me into drama, I would never have written - nor liked her so well in the first place, for that matter. I can’t even imagine tracking her down to ask how to unlock a chart note I accidentally locked or how to fix the thermostat in my office. HR would not at all be out of line to question what I was doing if I did that. Like, she doesn’t work here anymore and isn’t getting paid - leave her alone so we don’t have to worry about this!
I do feel you’ve gotten caught up in drama, OE. Not judging you, it happens to everyone and certainly it’s happened to me, but if you have concern for your demoted friend you should express sympathy to him. If he tells you Snake is systematically trying to destroy the company…I would still hesitate to react, assuming I valued my job. If you’re going to ask him, I’d ask it as an open ended question. “What happened?” and not lead him to blame Snake. That way if he sent a dick pic to an employee he can say so without getting paranoid that someone is out to get him on top of it.
