You are an entry on a spreadsheet. Nothing more. Your work, attendance, team spirit, participation in HR childish buffoonery, none of it matters. None.
Give the least amount of effort possible, and when you decide to walk for a different/better job because you no longer expect to spend a decade or more at one company, just walk out. No two weeks, no notice, nothing. Just a note and your all your equipment in a box.
You. Owe. Them. NOTHING.
