I was placed on an improvement plan in my last sales role.
I saw it as writing on the wall and spent my time and energy getting that next job lined up.
Because I left the company on my own terms, I controlled the narrative and actually took a step up in both base pay and the opportunity.
It’s something to consider.
PS – I should also mention that I earn more in my new role than I ever did in the previous one. The company went into receivership in the end and so it wasn’t me that was the problem, it was the management.
