U.S. COURT OF APPEALS
FOR THE NINTH CIRCUIT
SHARON TESLER, No. 24-5456
D.C. No.
Plaintiff - Appellant, 4:23-cv-00192-KAW
v.
MEMORANDUM*
UNITED AIRLINES, INC.,
Defendant - Appellee.
Appeal from the United States District Court
for the Northern District of California
Kandis A. Westmore, Magistrate Judge, Presiding
Submitted December 9, 2025**
San Francisco, California
Before: BUMATAY, JOHNSTONE, and DE ALBA, Circuit Judges.
Plaintiff Sharon Tesler appeals the district court’s grant of summary
judgment in favor of United Airlines, Inc. regarding her retaliation cause of action
under California Labor Code § 98.6. We have jurisdiction pursuant to 28 U.S.C.

This disposition is not appropriate for publication and is not precedent
except as provided by Ninth Circuit Rule 36-3.

The panel unanimously concludes this case is suitable for decision
without oral argument. See Fed. R. App. P. 34(a)(2).
§ 1291. We review the grant of summary judgment de novo. In re Oracle Corp.
Sec. Litig., 627 F.3d 376, 387 (9th Cir. 2010). Summary judgment is appropriate if
the pleadings, discovery, and any affidavits “show that there is no genuine issue as
to any material fact and that the moving party is entitled to a judgment as a matter
of law.” Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 247 (1986); Fed. R. Civ.
P. 56(c). We construe all justifiable inferences in the non-moving party’s favor.
Anderson, 477 U.S. at 255.
The district court properly granted summary judgment on Tesler’s retaliation
claim under Section 98.6. Tesler failed to establish the second element of her
prima facie case: whether United’s alleged actions constituted adverse employment
actions. See St. Myers v. Dignity Health, 44 Cal. App. 5th 301, 355–56 (2019).
For example, Tesler failed to point to specific charter flights that she was denied or
missed due to purported misinformation, or to demonstrate that the flights were
actually available when she requested them. Also, Tesler failed to show that the
lottery system for staffing the Charter Program was not fairly implemented, or that
her technical issues with Open Time were the result of targeted retaliation against
her that went unresolved despite her complaints. In fact, the record shows that
other employees also experienced technical issues with Open Time and that the
issue was resolved such that Tesler was eventually able to pick up flights through
the platform. As to Tesler’s assertion that United’s investigations into her
2 24-5456
complaints constitute adverse employment action, that argument too fails. Tesler’s
displeasure about how United conducted investigations is not enough to raise an
employer’s action to the level of an adverse employment action. See id. at 356
(“[T]he mere fact that an employee is displeased by an employer’s act or omission
does not elevate that act or omission to the level of a materially adverse
employment action.” (internal citation marks omitted)).1
Because Tesler has failed to raise any genuine issues of material fact as to
the second element of her prima facie case, her claim necessarily fails, and the
district court properly granted summary judgment in United’s favor. See Celotex
Corp. v. Catrett, 477 U.S. 317, 322 (1986) (noting that summary judgment is
required “against a party who fails to make a showing sufficient to establish the
existence of an element essential to that party’s case, and on which that party will
bear the burden of proof at trial”). As a result, we need not address Tesler’s claims
regarding protected activity, causation, and pretext. See INS v. Bagamasbad, 429
1
Tesler’s argument that her suspension pending a review of her fitness for
duty constitutes adverse employment action fails. Tesler’s Complaint in this case
long pre-dated her suspension, and thus she could not allege it as retaliatory
conduct absent an amendment. See Fed. R. Civ. P. 15(a)(2). But even if we could
consider this event, Tesler failed to provide any argument regarding causation or
pretext as to her suspension in the district court, thus she failed to carry her burden
of showing a prima facie case of retaliation and she cannot do it for the first time
on appeal. See Smith v. Marsh, 194 F.3d 1045, 1052 (9th Cir. 1999).
3 24-5456
U.S. 24, 25 (1976) (“As a general rule courts and agencies are not required to make
findings on issues the decision of which is unnecessary to the results they reach.”).
AFFIRMED.
