Would you say...
A. 2 years service award presented to
(Listing numerous people)

B. 2 years' service awards presented to
(Again will be lusting numerous people)

Two years service award, if in doubt leave it out. Or you could put two years of service.

(however, be careful who you’re lusting after)

Are you asking about years vs. years' or award vs. awards?

For the former, I would try plugging different numbers in there and see which sounds better to you.

1 year service award
2 year service award
20 year service award

or

1 year's service award
2 years' service award
20 years' service award

You could argue for the correctness of either, IMO.

Though

1 year service award
2 years service award
20 years service award

would sound a bit clumsy to me.

Award vs. awards, I think you could just pick which sounds better to you.

24-months' lusty servicing awards.

UPDATE
I want to say...
2 years service awards are presented to...then show a slide that lists the names
So Im thinking...

2 Years' Service Awards Presented to

Does it list the names of the people you're lusting after?

Tell us all about The Lust List.

It sounds....... fascinating and unusual.

2 years' service is correct

Yes, I agree.

I think you could say year or years' but why are posters mentioning awards, that's clearly a plural

2 years' service... Means 2 years of service so it's possessive and should have an apostrophe.
