Back in the day, severance packages for white collar workers were close to one month per year served. My father received that from Kodak (Not once, but twice... He had the rare privilege of being laid off (From the same team, no less) in 2009, and then again in 2016. The severance package did not change much between each of his stints of employment.)

With that schedule, anyone who worked at AirBnB for four years or less looks to be in a similar position.
