Hear me out..
If you really don’t want to be included in the layoff list, start applying for other jobs from your work laptop, and talk to your manager openly about it. Tell them that you’ve started looking elsewhere because the salary at Oracle isn’t enough for you and you’re feeling demotivated.
The idea is that they’ll know you may leave soon, so they may be less likely to include you in the layoff list, since letting you leave on your own could save them the cost of severance.
And even if you weren’t actually being considered for a layoff, and you later feel like you made a mistake by telling your manager you’re looking elsewhere because it could affect your promotion prospects, you’ve still communicated something important: that you’re feeling demotivated and dissatisfied with your current situation. At least they’re now aware that something needs to change if they want to retain you.
