The loot list on the Prime Tenacious Giftboxes from doing 5/7 Daily Contracts looks like this right now:

3-5 Gilda Stars
3-5 pots of Honorable Victory Rank 14
1-3 Adventurer's Growthstone(s)
1-3 Companion Growthstone(s)
3-5 Abyssal Shards
1 Worker's Compensation: 500

I've been doing my Daily Contract Quests every day, and I haven't seen these giftboxes drop any kind of labor pot since they were changed in the 3.0 update way back in December 2016.
