Twitter owner Elon Musk reportedly fired the senior staffers over the weekend.
  • Elon Musk fired four Twitter managers who were previously on a "do not fire" list, per Platformer.
  • It said their compensation packages included accelerated stock vesting, making them costly to fire.
  • The managers, including Esther Crawford, worked at Twitter for just over two years, per LinkedIn.

Four senior Twitter managers were previously put on a "do not fire" list because it would be too costly to pay them out, but all four were fired anyway, Platformer reported.
