Once I was asked to sign a one year contract after I returned from recurrent.
I said no thank you I served my (initial) year and I’m still here with every intention of staying.
They asked again after my upgrade training and I said no thank you that’s the cost of doing business.
My best advice is still to sit it out and take it as a learning moment.
You hear the sirens calling your name and you lay awake at night seeing seniority lists floating by no doubt.
Your reputation and your credit score will thank you.
I’m not saying they will but if you bail they have the option to send it to collection and collection agencies...well they couldn’t care less is the polite way of saying it.
