Omg man I'm in the Central Region....
When you transfer from PT to FT, you will be considered a newly hired FT employee.
You will have 2 seniority dates. Your PT seniority date will be used only to determine how many weeks you are eligible for after working the first year FT without a vacation......Sorry.
Central Region Supplement
Section 10-Part-time Employees Transferring To
Full-time Jobs Other Than Hub and Preload
Part-time employees successfully transferring to full-time jobs will
be considered as newly hired full-time employees and will be added
to the appropriate seniority list. Their seniority date will be the day
of the transfer.
ARTICLE 16-VACATIONS
Any employee who attains seniority must work an entire year in
order to be eligible for vacation. Once eligible, the employee will
select an available week between the eligibility date and the week
of Thanksgiving of that year. If there are no weeks available the
employee will be paid in lieu of time off. The Option week may be
taken after the completion of the eligible year.
