As I'm told by my company that me leaving would break the deal for everyone. That's not what I want, but it's also not a good deal for me (especially compared to other offers I get)
One thing you must understand about the sale of a business is everything is very quiet because everyone is afraid of being screwed over. The company you work for wants the sale to go through and to have their exit be fruitful after many years of work. The company buying your company would like to get all of the assets, of which you are one, and make the new entity profitable for them in some way. You want to be treated well and see an exit that you believe you deserve, and so on. This is a tough balancing act and unfortunately, not a situation most people treat very honestly. I was there! I know how you feel.
What I did was stayed until the documents were signs. I was officially an employee of the new company for one day. The companies were officially (from a legal standpoint) merged. I then went to my new bosses and said "Now that the companies are merged, I need you to make this right for me by giving me X, Y, and Z." They said, "No way, you have a job, get back to work." I then packed up my stuff and left to one of my other job offers. I got what I wanted. The company I had worked for got the exit they wanted. The new company wasn't very happy but never the less got the merger they paid for.
At any rate, your milage may vary. Situations like this suck! But remember deep down this is business. Do what you need to do to make yourself and your family or whatnot comfortable and happy.
As someone who has not been there and has zero experience in this, I'm left wondering whether you had more leverage to ask for "X,Y, and Z" before the deal closed. Not from the acquirer (avoid risking the deal), but from your employer. Surely if you explained the situation and how it is relatively unfair from your perspective, they might be able to negotiate on your behalf?
At any rate, the relationship deteriorated, which is not uncommon when a company is being bought or sold. We kept our smiles on until the acquisition was complete.
Have you participated in startups since then? Did you take any extra precautions after this experience?
I have been involved in start ups in two ways in the mean time. First, I have built up and sold my own small start up. This was much easier though as I was the sole owner and employee. Throughout my time building it up I did occasionally hire contractors and consultants on a 1099 basis. Overall, this made selling the company and assets a whole lot easier.
Second, I have worked for start ups, quite a few actually. But at this point I actively will not take an equity stake in any start up I work for. I always work hourly and get paid my standard rate for any work produced. In this time I have been involved with two start up sales. They were much easier on me, the owners, and the acquirers. Basically, I had been paid all along what I felt was fair so I didn't try to get anything out of the arrangement as it was being sold. I could be very focused on the owners best interests and not my own. In the end, both gave me substantial bonus amounts for my help and trouble and we all walked away happy. I also contracted with both of the acquirers after the fact in these cases. Again, everyone was quite happy.
I suspect that if you are part of the deal, if you wanted to work for the acquiring company, you could have already gotten a job there long ago. Clearly they were not your first choice of places to work. The terms that are being offered don't change that, and perhaps no terms can.
That's o.k.
If there is really nothing at all that would make you stay, then I don't think you're obliged to stick around. But you might want to talk with a spouse/friend/family member before making that decision.
Good luck!
There is some package of wage and conditions that you would accept. If they're not offering that then it's entirely on them if you leave, not you.
If the acquisition deal hinged upon you staying and if you want to go, then too bad. The deal is off. That's not your concern. If that means that your (former) employer crumbles, then so be it.
Regardless, your old company can't compel you to go work for a new employer. Morally or legally.
Alternately, what's to stop you from accepting the deal and then leaving in 4-6 months anyway?
When I recently switched from a startup for a 30% raise, the CEO was pretty hostile. It actually made me feel better about leaving.
If you want to be polite, give them a chance to counter-offer, but you already told them that you thought you were underpaid, so you don't owe them that.
Also, if you get an offer that says "You get $X when the merger closes.", what happens if the deal falls through? What happens if the close date gets pushed back for a year? Remember the time value of money; you would have been better off taking the other offer if that happens.
I've seen it happen numerous times, and experienced it.
Will your compensation be > SUM( everyone's compensation)?
You are not a slave.
