Out of my 20 YRS of IT exp, I spent 14 YRS in ACCN. Have worked as Team Lead, Associate Manager and Manager there. I have ran few PIPs incl some close friends (but couldn't save them). So I'll try to help you choose the best option for your query. There's no escaping once you're chosen for PIP. 99% you'll fail the tasks and will be asked to resign. You'll be given 3 months severance pay and sent out. Nothing negative in the records. All clean. In very rare cases, if you're critical resource, current project will fight and project MD has to intervene with HR to clear your PIP. Hardly 1% chance for that.
