Sorry it's taken me so long to come back to my thread. I really appreciate everyone's responses massively.
I can't respond to everyone individually but, just to clarify on the main themes - I most definitely spoke up for myself in yesterday's meeting. I was a little shocked initially, partly because I was ill-prepared, and partly because I couldn't believe what I was hearing. I'd received a fairly informal email from line manager (LM) first thing, just saying 'Can we get together later to talk about X customer, does 1pm suit?'. I naturally assumed he wanted to set aside the time to talk about what I'd raised/what had gone wrong/why it had gone wrong/how we could rescue it etc.
I went to his office a little before 1pm, and was surprised to see the Director (D) go in before me. He's not generally visible around the workplace and, in fact, I've only met him two or three times. I was called in, and invited to take a seat which all felt a bit weirdly formal compared to our normal dynamic.
As I said in my OP, the general message was 'how has this been allowed to happen/what went wrong/we need to put swift measures in place' etc etc.
When I gathered my wits, I was very vocal about how I had first raised a concern back in November, that I had pointed out that we were facing a tricky situation, and it required attention. I said to them that I had anticipated a complaint (I didn't have exact date to hand, but I knew it was early Jan) but that things had been too slow to progress.
At the close of the meeting, D thanked me for my input into Customer X. My final point in the meeting was that this complaint had been completely avoidable, and he acknowledged that.
This might not surprise you but, even at my age (47), I'm still quite unfamiliar with the dynamic of workplaces. I worked very part time in low paid/low skilled work while my DCs were little, and it's only two and a half years ago that I've returned to the workplace "properly", so to speak.
That said, I have built up a reputation for myself in this firm for being competent and solid, and I know that I'm highly regarded. I'm on a fairly low pay grade, but that's entirely by choice. I'm happy at the level I'm at, and I know I can do my job well without any added pressure.
To give an update on today's events, I have gone with the confusion angle. I emailed D this morning, just saying I was glad to have the opportunity to discuss the X customer situation, that I thought I had acted in accordance with the company's escalation process when I raised my concerns, but that perhaps he could advise as to how I could have acted differently.
I got a short, but friendly, response - which pretty much thanked me for acting in accordance with reporting channels, and acknowledging the work I'd put in with customer X.
It was a little insipid, but I think that sums him up, generally.
I haven't spoken to LM at all today. I work in a small, open plan office, so it's difficult to get a word with anyone privately - unless you ask for a private word upstairs. He hasn't been particularly communicative with me today but, in fairness, that can be normal on busy days.
My last question is this. I would like to have a conversation with LM along the lines of "you threw me under a bus on Thursday, didn't you?". I feel like the best approach is to face it head on, and I'm confident enough to be able to do that. But, obviously, his response will be along the lines of "no I didn't".
I know I've got choices here, and I know that I'm in a fairly strong position.
Choice 1: I can battle back on this, knowing that the D recognises my worth. I could send that email trail (even although the D considers the matter resolved), and enter into a tricky dynamic with LM. I'm not sure how this would resolve itself?
Choice 2: I can rest easy, knowing that D values my worth to the company. I can rest assured that I acted in accordance with escalation policy, and that I cannot be seen as culpable here.
Let's be honest, LM fucked up big time - he knows it, and I know it. And I'm certain that D knows it too.
I'm tempted with going with this. Partly because it's the easiest, I'll admit that. But also because I need to be able to work with him in the future. I know how feeble that sounds, but I've got reasons
. The office is local to me, I adore my job, I'm good at it, and I can pretty much choose my working hours to suit.
I'd appreciate anyone's thoughts.
