I think anyone with 365 days or less since their hire date is probationary. So this will have a totally unbalanced impact because some WFOs probably have 0 people with that status and some probably have 2 or even 3 in rare cases so that impacts them very differently. I actually personally know 4 people who got terminated during their probationary period in the NWS since 1992. One for just being the hostile person they were and still are, a second for breaking vital equipment, one for entering the office during off hours intoxicated (they mistakenly told the taxi that was their house), the other for being just awful at the job and having some personal issues with mental health (they should never have been let go and gotten the help they likely needed).
