Also known as: MeetingTetrisSchedulingNightmareBackToBack

The complex puzzle of scheduling meetings around existing commitments, often resulting in back-to-back calls with no breaks.

Origins

Emerged from knowledge worker complaints about meeting proliferation 2018-2019. Microsoft Outlook’s color-coded blocks visually resembled Tetris. Google Calendar’s emoji reactions (2017) added to gamification metaphor.

Peak Problem: 2020-2021

Remote work eliminated hallway conversations, replaced with formal meetings. Microsoft reported:

  • 2x increase in weekly meetings per person (Feb 2020 to Feb 2021)
  • Average meeting length decreased 20% (brevity via back-to-back scheduling)
  • After-hours meetings up 28% (timezone sprawl)

The 30-Minute Tyranny

Calendar defaults to 30/60 min blocks, so 25-min conversations ballooned to 30. Google added “speedy meetings” feature (2017): default 25/50 min to allow breaks. Few used it.

Solutions & Workarounds

Tools:

  • Calendly, Clockwise (smart scheduling)
  • Reclaim.ai (AI calendar defense)
  • “No Meeting Wednesday” policies
  • Meeting-free mornings (protected deep work)

Cultural shifts:

  • 15-min default meetings
  • Async-first communication
  • Meeting audits (required justification)

Manager vs Maker Schedule

Paul Graham’s 2009 essay resurfaced: managers operate in 1-hour blocks, makers need 4-hour chunks. Calendar tetris revealed tension - one meeting ruins maker’s day.
