I generally disagree with the above sentiments.
If the deal gets rejected escalation is the only logical consequence because all the things currently in place (TB, CC) have not worked since 2014 (?) Our timing would have to be very lucky if the TB was to make the crucial difference in the next few months, if it has not made the difference since it's inception..
To vote "YES" because you have had enough, want some peace and generally think this is as much as we can get, makes sense and is the low risk, low return option.
To vote "NO" because you think you can create more leverage through action to get an improved deal makes sense but you got to be prepared to do stuff that are rather uncomfortable.
To vote "NO" but not to be prepared to back the keyboard warriordom up with action and think by doing more of the same for a few more weeks and hope the company will suddenly give in and us having the negotiating edge is naive in the extreme ! To vote "NO" and not be prepared to escalate makes no sense at all and you better abstain from the vote.
