Five of Madonna's staff have walked out on her.
Two personal assistants, two nannies and a chauffeur - who all cited long working hours as the reason for quitting.
Last week nanny Angela Jacobson quit and was immediately told to leave.
Another nanny, Elodie, who had worked alongside Angela looking after the singer's three children - Lourdes, 12, Rocco, eight and adopted David, three - has also quit.
They are joined by personal assistants Denise Lambertson and Johanna Edholm, and chauffeur Alistair Mitchell, who was Madonna's driver for seven years.
Angela posted to her Facebook profile:
"Not putting up with this shit anymore. Never have, never will. Standing up for my rights regardless of consequence. Sick of always being the one who compromises."
Angela, who was contracted to work until the end of June, is said to be shocked she was told to pack her bags almost immediately after revealing her plans to leave.
"Angela was with her for two years and was particularly close to David. He and Rocco are devastated she is leaving. And Elodie, who's been with Madonna for about 15 months, was also close to the children. But all Madonna's employees work incredibly long hours," a source told Britain's People newspaper.
Johanna said because of the long hours working for Madge, her boyfriend left her.
And to throw for salt in wounds, Alistair left Madonna to drive her ex-husband Guy Ritchie.
