I have an epic FU story, but I did not have the FU money at the time to back it up, and its something that has come back to bite me in the ass over the years (small field). I still don't care and I'd do it the same way.
I worked for a private medical group that consisted of 11 people, with 5 of them being partners. They made all the decisions, they directed the employees when to work, they made 2x as much for the same job and they took 8 weeks of vacation a year while offering the employees 4. Basically any time a partner called you, you'd be getting reamed out, or told for whatever reason why you were to be the one doing the work that day while they sat on their asses.
I'd worked for this company for 3 years when things started going south. Partners were grumpy, they started acting real nervous. The company party was canceled, they had a meeting and told us there were financial problems. One of the partners was a dolt and had been put in charge of a contract that none of the other partners wanted to do. Dolt proceeded to generally fuck things up and they lost the contract. It had provided over 4 FTEs and they were sweating it. They didn't want to get rid of anyone because that would mean they'd have to do more work, so I think they slowly let the company coffers run dry.
A few months pass, and they let us know that they're going to have to let go of 2 people. They're "going to start asking around and soliciting feedback on everyone" so just hold tight and wait to see if you're listed as either of the 2 people (out of 6 employees) getting canned. I've been watching this, and having asked a lot of questions am acutely aware that canning 2 people will not make up for the loss of 4 FTEs.
At this time I'm pregnant, and one of the Doctors we work with invites me to their Christmas party because we're fairly friendly. Since the party is hosted at his partner physician's house, I pull him aside and ask if I can come to the party because I was invited by physician 1 and I didn't want to crash his house without him knowing I'm coming. It turns into this HUGE shitstorm where he's apologizing because he accidentally snubbed our entire group, he hadn't intended to forget us etc. He calls the partners to apologize and invite them, and I'm hung out to dry. The partners call ME, tell me that I've embarrassed the entire group, we could lose more contracts as a result of this etc etc. Later on that week in the middle of a clinical day I get told that I'm being pulled out of my patient assignment to have a meeting with all of the partners. I thought I was going to be fired on the spot. I called my husband, had him run to walmart and buy me a voice recorder and go to this meeting. In the end they just grilled me, harassed me about what an embarrassment I was and let me go back to taking care of my patient. I was totally fried, terrified, shaking etc.
Incident 2 regarding this employer. When I announced that I was pregnant, things had already started to go bad financially. They were obviously very annoyed that I'd dared to have another child (already had 1 baby while employed there), and when I told them my intent to take 7 weeks off and return like the previous time, I was told "you do not tell us what you will be taking. you can ask and we will let you know what's allowed. we did not appreciate your attitude and your assumption that you could do that stretch of time". I got a ton of shit over the phone, had multiple partners calling me, this one particular lady was horribly bitchy and was always tasked with being the awful disciplinarian with everyone. So I cry on the phone, say I don't understand why its a problem this time, and they let me know that 2 of the partners had already scheduled vacation for my anticipated leave time and that I must be back because they could not change their plans and we had to have enough people to cover our patient needs. I was also told that since vacation accrues during the year and cannot roll over to the next, I hadn't already earned the time or the right to be off for the current year.
The partners finally name 1 person who is going to be canned and give her 2 months notice so she can find a new job. They tell everyone that they like us all so much its so hard to decide that they just can't pick a 2nd person. I'm sitting there pregnant, evaluating the 2 incidents I listed above and realizing there's a good chance that they want me gone, but legally can't get rid of me while pregnant. So I have my baby, go on leave, interview for jobs while on maternity leave. The horrible bitch lady's oldest son is getting married on a Saturday so I give my notice to quit 2 days beforehand. I send them all an email titled "new employment" that says "I've taken a new job, my last day is X" and nothing else. A shit storm of phone calls occur and everyone's telling me I can't just give notice via email, that I'm burning my bridges, this is a small field and everyone knows everyone and it could hurt me etc. I know it ruined bitch lady's ability to relax and enjoy her precious poopsie's wedding and I would do it again IN A HEARTBEAT.
I know I should have done something legally regarding the pregnancy leave but I figured no matter what happened (if I had pursued something) they would have had justification for getting rid of me as the 2nd person. I let it go because I was naive and just wanted out. These people also harassed a coworker when she was assigned jury duty (also illegal!)
A follow up to the company - a 3rd employee left when I did and they were down to 8 employees. They never rehired, they clearly didn't have the money. The hospitals eventually got sick of them and told them their contracts weren't being renewed. The company folded and the partners all went to work as hospital employees with a fraction of the money or benefits they had earned by stiffing us employees. Good riddance to them. I still get nervous when I visit friends in that old town that I might run into bitch lady at Target or something, and whether I'd be ready to tell her off that I should have sued her.
