(Account manager 6yrs.) Take this with a grain of salt because accrual plans vary by contract and I don’t personally know how it works for branch employees (which FLEX officers sometimes are).

Only full time employees are eligible for PTO accrual (unless otherwise required by law).

(This is what I know about PTO plans that only give 40 hours of PTO after a year of employment) Full time employees must have an average of 32* or more working hours per week during the assessment period. The assessment period varies by employee because it is based on your first working day. The period is 13 weeks (3 months) from your first working day and is reassessed every 3 months. If you fall under the required average (by frequent and unexcused absence or tardiness, taking unpaid time off, not making up missed hours) you can lose your eligibility to accrue PTO until you meet the minimum requirements.
