Pearson hasn’t offered 1 month per year of service in severance packages in over a decade. A typical package is two weeks per year of service for most staff; high-earners and senior execs get three per year of service. Some include health insurance for the duration of the package, and a few can negotiate other concessions.
If the unfortunate happens, don’t sign anything right away - take the time to read everything, and maybe even pay a lawyer to look it over for things you might miss, or want changed before you sign. It never hurts to ask - I know someone who got their health insurance paid out for a full year, longer than the severance payments themselves.
