FMLA, according to the law as-written, can be taken in increments of weeks/days/hours which means you're legally entitled to a partial day. Considering you're requesting a partial day wherein the company knows the day/time
in advance each week, they should be able to compensate with an earlier start-time and/or moving stops off of you.
I've been told in the past that the company doesn't have to comply with that in package car, but I disagree. If your center manager isn't complying, I would contact your BA and HR. I've personally witnessed HR force managers to double over backwards to comply with FMLA as UPS doesn't want to deal with the backlash of FMLA enforcement. You're not asking for the
ing world here, you just need to talk some stuff out with somebody and they need to respect that.
