Obviously your problem is political, not your actual job skills. How good is the gossip line at your office? The issue is, how many people got raises and what was the average raise?
Lets assume everyone got raises and you got one of the lowest raises in the office. We also know you are one of the new guys, not having been there very long.
Now lets look at third quarter payroll costs versus sales forecasts and assume some layoffs in 3rd quarter may be needed. If you know you are going to have to lay some people off, to reduce your costs you start trying to drive people out now. No severance or unemployment for those who quit.
Who do you target? People who are capable of independent thought. Short timers. Non-Team players. People who do not need the job as badly. People who may be difficult after the layoff takes place. People with families will complain less after the layoffs, when the teams are smaller and working more to cover lost co-workers.
Translation, kill the wolves keep the sheep. You ain't no sheep.
Advice, keep interviewing and no matter what they do or say, you show up every day on time, smile, no chit chat since you know you are leaving anyway, and for god sakes no questions during large team meetings. Just be quite and smile a lot. That way they will think you have come over to their side. The look on their faces will be priceless when you resign.
This is only one scenario.
