Our 2026 Holiday Calendar:
How We Recharge
How We Handle Holidays
At Mass Additive, we do things a little differently. We believe that to provide the highest quality service to our clients, our team needs time to truly unplug and reconnect with their families and friends. To balance this, we distinguish between Observed and Celebrated holidays:
-
Observed Holidays: These are our "Rest & Recharge" days. All operations—including production, shipping, and communication—will pause.
-
Celebrated Holidays: These are "Work & Party" days! We remain fully operational, but we take time on-site to honor the occasion with our team through special events.
