Should She Omit Her Failed Probation?

I’m reaching out to fellow recruiters for advice on a situation concerning my partner. She is 32 and has spent three years in customer service for a well-known fashion brand, followed by 2.5 years in the marketing team. After dealing with some internal politics and toxic behavior from new hires, she decided to resign.

Two months later, she joined a different company as a marketing manager in the food and beverage sector, but unfortunately, she just learned that she did not pass her probation period. I’m wondering if it would be wise for her to exclude this short-lived position from her resume. My concern is that a three-month role with a probation failure might deter potential employers or recruiters right from the start.

I would appreciate any insights or advice on this matter! Thank you!
