W4 Adjustments - New Job, but On Old Job Payroll

Hi all,

 

Having some trouble with my W4s.  I just started a new job, but I’m still on payroll for the next few months with my old job because they’re paying out my accrued leave biweekly instead of as a lump sum.  Should I file my W4 with my new and old employers as if I have two jobs, or leave my W4 at my old job as-is, and file my W4 with my new job as if I only have a single job?
