to think that those working a four day week should also get 'summer office hours'?

[SteelMagnolia]

For June/July/August, that's 13 weeks, employees at my company (800 employees, public company) get to leave at 3pm. Normal leaving hours for Fridays are 5pm, so that is 2 hours off. So, over the three months, that is a total of 26 hours off.

I don't work on Fridays. I work Mon-Thurs. My salary, bonus, public holidays, etc are all 4/5ths of what it was when I was full time. I assumed I would be entitled to some kind of summer concession, to equal 4/5ths of 26 hours, which is 20.8 hours. I sent an email to my HR rep today asking if they'd decided what to do about summer hours for those not working Fridays (there are several mums in the office on a reduced schedule.)

My HR team's response, via an official "summer hours Q&A" she attached to an email:
'Q: What happens if I don?t work on a Friday?
A: Lucky you! That?s just one of those things unfortunately; you won?t be able to carry over to another day."

However the Q&A says they ARE going to make concessions for people who are unable to leave early on Fridays because of their duties. So, they are making some adjustments.

AIBU to think this is not right? (And to be annoyed at the language they used, ie "Lucky you!" Anyone not working Fridays probably have kids and ARE working their butts off that day, at home!)

OP, YANBU. You should get pro-rata, as many other posters have said. That's how it goes at my workplace too. BTW I am another one who doesn't work Fridays, but I have two PT colleagues, one of whom doesn't work Mondays, the other who doesn't work Wednesdays. Sounds as if we were at your workplace OP we would all have different holiday entitlements!
Surely the issue isn't full time vs part-time. I am at the part-time bashing going on here.

All those people who are jealous of part-time workers - why don't YOU ask for reduced hours and the reduced pay packet that goes with it? Or leave your full-time job and seek a part-time role with another company?

If you want part-time hours, apply for them, just as your colleagues who work part-time did.

I think I'll keep quiet about the pro-rata Bank Hols. As there are only one or two that ever fall on a Friday I'm probably better off, as I get 100% of the Monday ones.

Quick update: I emailed my HR contact today, just to clarify the policy and ask about the process they went through to come to that decision. As luck would have it, all of HR was at an offsite today. But I mentioned it (as casually as possible) to the woman that runs our department (about 60 people) and she said that the HR policy is nuts. She said that they are giving some free holiday time to those who cannot leave early on Fridays due to job obligations, and that they would certainly do something as well for part time workers. So, no matter what HR thinks, it is great to know I have her support!

Seems bizarre to me that they give away any time at all, most companies would have flexi time & say yeah in summer leave early if you like if you have built up the time.

It was funny--they said in the Q&A that the "Friday bar" will be open sooner than usual with summer hours. I had no idea that existed! Obviously a new thing since I've gone part time! I know, now it sounds like a party, with early summer hours and a Friday bar! Don't be too jealous, it is an insane place to work despite the perks they are trying to build in. :)
