Appellants Ivan Ruiz and Estela Díaz, husband and wife, challenge various district court rulings relating to their claims against appellee Posadas de San Juan Associates, Inc. (“Posadas” or “Hotel”), alleging, inter alia, age discrimination under the Age Discrimination in Employment Act (ADEA), 29 U.S.C. § 621 et seq., and Puerto Rico “Law 100,” 29 L.P.R.A. § 146 et seq. As we conclude that appellants failed to generate a trialworthy dispute regarding their federal claims, we affirm the district court judgment.
I
BACKGROUND 1
In 1985, appellant Ivan Ruiz began work as a housekeeper at the “Hotel San Juan & Casino” (“Hotel”), owned by Posadas, a New York corporation. By 1987 Ruiz had been promoted to Team Leader, Housekeeping Department, responsible for supervising housekeeping in Hotel “public areas” (e.g., offices, meeting rooms, gymnasium). Beginning in 1991, he worked five nights a week on the 8:00 p.m. to 4:00 a.m. shift.
As a Team Leader, Ruiz received mixed performance ratings. During the period from 1987 through 1993, the average annual performance rating Ruiz received ranged from lows of 3.30 in 1987 and 1989, to a high of 4.02 in 1990. 2 Ruiz received regular salary increases throughout his tenure. In addi *246 tion, he received three merit certificates for excellent supervisory performance and a “good” overall rating in 1992.
During his tenure, however, Ruiz received some criticism. In 1988, he was criticized by Felix Joseph, his supervisor at the time, for “total negligence ... or total and complete disregard of ... Company Policy or both,” following an unannounced one-day absence from work. In 1990, a different supervisor, Eddie Ortiz, noted “major cleaning deficiencies” in the areas for which Ruiz was responsible — specifically, trash not picked up, rooms not cleaned, and furniture not dusted — as well as a general “lack of attention” to cleaning responsibilities in the Hotel corporate offices. Finally, in 1993, yet another supervisor, Jorge Serrano, warned Ruiz about poor cleaning in the gymnasium and filed a contemporaneous disciplinary report against him.
Ruiz, on the other hand, dates most of his employment problems from late 1993, when Luis Rivera, age 32, became Hotel Executive Housekeeper. Rivera regularly criticized Ruiz, verbally and in writing, on his job performance. 3 In March 1994, Rivera rated Ruiz’s performance for 1993 as “need[ing] improvement” in three areas: accepting criticism, solving problems, and quality of performance. Rivera noted that Ruiz blamed others for his own deficiencies, responded lackadaisically to guest requests, and provided inadequate supervision to subordinates. After Ruiz complained to Rivera, the performance evaluation was changed from “need[ing] improvement” to “satisfactory,” but Rivera did not soften the negative written commentary. The average rating Ruiz received for 1993 was 3.69. 4 See supra note 2.
Beginning in 1993, Victoria Greber, Executive Assistant Manager, “Rooms Division,” likewise complained that Hotel public areas were found to be untidy following Ruiz’s shift. Felipe Mercado, the night manager ultimately responsible for supervising Ruiz, complained directly to Greber about uncleanliness in areas for which Ruiz was responsible. Other unfavorable comments relating to the untidiness of Hotel public areas following Ruiz’s shift were noted in the Hotel log books — daily diaries describing, inter alia, the physical condition of the Hotel — by various Hotel employees including Rivera.
During the Spring of 1994, the occupancy rate at the Hotel dropped dramatically, resulting in severe shortfalls in Hotel revenues and prompting work-force reductions by the administration. In May 1994, Greber met with Rivera and Egidio Colón, Human Resources Director, to evaluate the personnel records of all employees holding an employment position within any category targeted for reduction, which included a Team Leader position in the Housekeeping Department, “Rooms Division.” 5
After the personnel file on each Team Leader in the Housekeeping Department had been reviewed, and following receipt of input from Colón and Rivera, Greber determined to discharge Ruiz. According to both Colón and Greber, the dispositive factors were the negative written evaluations (Ruiz posted the lowest average scores of any Team Leader), the negative commentaries, the disciplinary *247 warnings, the complaints from night manager Felipe Mercado, and the negative log-book notations regarding the uncleanliness of the public areas following Ruiz’s shifts.
On June 2, 1994, Ruiz was fired, after being told that the Hotel was undergoing “reorganization,” and “adjustments” in the “Rooms Division” were necessary. Following Ruiz’s dismissal, supervisory responsibility for the night shift was divided between Carrasquillo and Waters, both of whom continued to serve as Team Leaders on their daytime shifts as well. 6
On June 7, 1994, Ruiz filed age-discrimination charges with the Equal Employment Opportunity Commission and the Antidis-crimination Unit of the Puerto Rico Department of Labor, requesting reinstatement. On November 18, 1994, a preexisting Team Leader position in the Housekeeping Department became vacant when Mr. Rosado, see supra note 5, was promoted to Public Areas Manager. The Hotel did not inform Ruiz of the vacancy, however, instead promoting Alexis Vargas, age 26, to Team Leader.
On March 24,1995, his administrative remedies exhausted and a “right to sue” letter in hand, Ruiz (and spouse) filed a complaint in the United States District Court for the District of Puerto Rico, alleging that the Hotel, during 1993-94, had a policy of discharging older employees, in violation of the ADEA and “Law 100.” Following extended discovery proceedings, the Hotel moved for summary judgment. In their opposition, appellants asserted, for the first time, that the Hotel’s failure to rehire Ruiz, and its hiring of Vargas, likewise violated Puerto Rico “Law 100.” Thereafter, appellants sought leave to amend their original complaint to state additional ADEA claims, alleging a failure to rehire based on age and claiming retaliation in response to Ruiz’s filing of administrative charges against the Hotel.
The district court granted summary judgment for the Hotel, after determining that the proffered evidence on the ADEA discriminatory discharge claim was inadequate for a
prima facie
showing that the Hotel either failed to treat age neutrally or replaced Ruiz with a younger worker,
see McDonnell Douglas Corp. v. Green,
II
DISCUSSION 7
A. Wrongful Discharge Claim Under ADEA
1. Prima Facie Case
Our analysis is governed by the familiar burden-shifting framework enunciated in
McDonnell Douglas,
2. Pretext
In order to rebut the presumption that arises upon the establishment of a
pri-ma facie case
— i.e., that the employer engaged in intentional age-based discrimination,
see Woodman,
There is no dispute that the Hotel experienced significant financial difficulties in the Spring of 1994 and terminated ten employees as part of a legitimate RIF.
8
Moreover, Victoria Greber, the executive directly responsible for the decision to discharge Ruiz, attested that financial difficulties prompted the employee discharges, both in her own department and throughout the Hotel. She explained, again without contradiction, that she determined to discharge a Team Leader in the Housekeeping Department because she considered it an expendable “medial” position between the housekeepers, who do the cleaning, and the Hotel management. She further explained that Ruiz was selected for termination because his employment record was the weakest among all Team Leaders. Careful review bears out that Greber’s explanation is entirely consistent with the undisputed documentary evidence that Ruiz had received more disciplinary warnings, and the lowest average evaluation ratings, of any Team Leader in the Housekeeping Department, as well as the only negative written commentary. Thus, the Hotel met its burden of production under the second prong of the
McDonnell Douglas
test.
See LeBlanc,
Accordingly, the presumption of age discrimination has vanished,
see id.,
and we inquire whether the evidence,
“in its entirety,”
would permit a reasonable factfinder to infer that the proffered reason for the dismissal was pretextual
and
that the true reason was an age-based animus,
see id.
(emphasis added). In pursuing this inquiry, we focus on whether the employer believed that its proffered reason was credible.
See Mesnick v. General Elec. Co.,
Ruiz attempted to demonstrate that Rivera was responsible for an atmosphere of age-based discrimination, in the Housekeeping Department, which influenced the decision to terminate him. He relied on an affidavit from Carmen Peña, age 54, formerly employed in the Housekeeping Department, who attested that Rivera expected more from her than from younger workers; asked her age; stated that she didn’t look good for her age; inquired about her health and suggested that a job change might be beneficial. Peña acknowledged, however, that Rivera never asked, let alone ordered, her to transfer. Moreover, Peña attributed another remark to Rivera — that all female workers at the Hotel were
overworked. In
addition, the Moreales affidavit states,
inter alia, see also swpra
note 9, that Rivera harbored an “obvious” bias toward younger workers. The only explication Moreales offered for this conclusion, however, was that Rivera had pressured older workers, unfairly reprimanded older workers in front of younger ones, and treated two older supervisors, including Ms. Peña, in a “disrespectful manner,” but without providing an evidentiary foundation upon which it might reasonably be inferred that any pressure, reprimand, or disrespect was either discriminatory or age-based.
See LeBlanc,
Although we have allowed as how circumstantial evidence of a general discriminatory environment may add “color” to an employer’s decisionmaking process,
see Conway v. Electro Switch Corp.,
Furthermore, as we have stated repeatedly, we do not assume the role of a “super personnel department[ ], assessing the merits — or even the rationality — of employers’ nondiscriminatory business decisions.”
Mesnick,
For the foregoing reasons, we hold that Ruiz failed to proffer competent evidence adequate to ward off summary judgment on the ADEA claim for wrongful discharge.
B. The Motion to Amend
Ruiz next contends that the district court erred in denying the motion to amend the complaint, see Fed.R.Civ.P. 15, to include ADEA claims based on the Hotel’s allegedly discriminatory and retaliatory failure to rehire him. See supra p. 247.
1. Standard of Review 11
As Ruiz did not propose the amended complaint until seven months after the Hotel had moved for summary judgment, we treat the motion to amend as “an attempt to alter the shape of the case in order to defeat summary judgment.”
Glassman v. Computervision Corp.,
2. The District Court Ruling
Ruiz contends that the district court confused the requirements an ADEA plaintiff must meet to establish a
prima facie
discriminatory discharge claim, with the separate standards for establishing
prima facie
claims of retaliation and discriminatory failure to rehire. He points to the district court’s statement that the retaliation and failure-to-rehire claims, “even if supported, will not sustain an ADEA claim. That is, plaintiffs would [sic] have established a
prima facie
case of age discrimination[,]” and argues that the district court erroneously ruled that Ruiz could not prevail on the proposed
retaliation
and
failure-to-rehire
claims because he could not meet the
prima facie
showing required for a
discriminatory discharge
claim. We need not address this contention, however, as the record discloses an adequate alternative ground for affirmance.
See Resolution Trust Corp.,
Given the tardiness of the motion to amend, the question before us is whether Ruiz supported the proposed amended complaint with enough “substantial and convincing evidence,”
id.,
of an age-based discriminatory animus.
See Woods v. Friction Materials, Inc.,
In addition, the essential thrust of the proposed amended complaint is that — coupled with Rivera’s alleged discriminatory animus toward older employees — the decision to hire Vargas, rather than recall Ruiz, was patently irrational and, therefore, must have been a pretext for discrimination. However, the underlying thesis — that Vargas’s qualifications were so inferior that the Hotel could only have been engaging in age-based discrimination and/or retaliation against Ruiz when it chose not to notify or rehire him — is seriously flawed.
First, Ruiz did not proffer sufficient evidence to enable a finding of discriminatory animus, either in the Housekeeping Department at large or toward him in particular.
See supra
pp. 249-50. Second, the fact that Ruiz, based on experience and past performance, may have been
qualified
to hold the Team Leader position which was given to Vargas, is
not
evidence that the Hotel was motivated by an age-based animus in withholding it from Ruiz.
See Woods,
In conclusion, whether or not it was shortsighted to bypass Ruiz in favor of Vargas, who had never received a disciplinary warning, it cannot be said that it was so absurd as to defy rational belief.
See Lehman v. Prudential Ins. Co. of America,
Therefore, as Ruiz proffered insufficient evidence from which an age-based discriminatory animus might reasonably be inferred in connection with the Hotel’s decision to promote Vargas, rather than rehire Ruiz,
see Smith,
Ill
CONCLUSION
Finally, since the district court supportably dismissed the federal claims, it permissibly declined to retain,
see
28 U.S.C. § 1367, supplemental jurisdiction of the pendent claim under Commonwealth “Law 100.”
See United Mine Workers of America v. Gibbs,
SO ORDERED.
Notes
. The material facts in genuine dispute are related in the light most favorable to appellants, who opposed summary judgment.
Velez-Gomez v. SMA Life Assur. Co.,
. On a scale of 1 to 5, “3" indicated that standard job requirements were met; “4" that the requirements were exceeded "in many instances”; "5" that the requirements were "consistently" exceeded.
. For example, in February 1994 Rivera notified Ruiz that many complaints had been lodged regarding the Hotel offices and that inspection had disclosed failures to dust, pick up trash, clean window areas, and clean bathrooms. Rivera warned Ruiz that he expected “immediate action” and that "[Qailure to comply” would "result in disciplinary action.”
. The annual ratings Ruiz received during his tenure were:
Evaluation Score Comparison to Rivera's Date Rating of Ruiz for 1993 calendar year
03-02-94 3.69 the rating given by Rivera
11-12-92 3.68 lower than Rivera's score
11-01-91 3.39 lower "
10-30-90 4.02 higher "
11-10-89 3.30 lower ” " ”
07-30-89 3.47 lower ”
01-06-87 3.30 lower ” " ”
.At the time, there were four Team Leaders in the Housekeeping Department: John Waters, age 61, Steven Rosado, age 27, Carlos Carrasquillo, age 34 — all of whom worked the day shift — and Ruiz, age 61, who worked the night shift only. Carrasquillo and Rosado had less seniority in their respective Team Leader positions than Ruiz. Rosado had been a Team Leader for only seven months, and Carrasquillo had become a Team Leader one year after Ruiz.
. The Hotel fired ten employees in all; two within the protected age group, including Ruiz. Ruiz was the only Team Leader in the Housekeeping Department to be fired. Two nonsupervisoiy employees in the same department were fired, aged 25 and 29.
In addition, another 111 employees left the Hotel between April and June, 1994. These included temporary employees whose contracts were not renewed; retirements; resignations; and terminations for cause. Among these 111 employees, nine (i.e„ 8%) were 40 years or older.
. We consider the summary judgment ruling
de novo,
viewing the record in the light most favorable to Ruiz, the nonmoving party, and drawing all reasonable inferences in his favor.
LeBlanc v. Great American Ins. Co., 6
F.3d 836, 841 (1st Cir. 1993). On the other hand, we must affirm if the record reveals no trialworthy issue of material fact and the Hotel was entitled to judgment as a matter of law.
See id.
Moreover, we may affirm “on any independently sufficient ground.”
Polyplastics, Inc. v. Transconex, Inc.,
. Ruiz so concedes on appeal. See Brief for Appellants at 14 ("Ruiz does not contest that a reduction in force was necessary in order to confront the Hotel's economic problems....”).
. An affidavit from Miguel Moreales, formerly a housekeeper with the Hotel, concludes that Ruiz was an excellent supervisor, but does not purport to compare Ruiz’s work record with that of other Team Leaders. Moreales also opines that Ruiz’s disciplinary warnings were unfounded because Ruiz always assigned a housekeeper to clean, and checked the area afterward. However, these conclusory statements did not demonstrate that the areas about which Ruiz was warned had been properly cleaned on the
particular
occasions identified in the warnings he received, much less that the warnings were unfounded, nor that Victoria Greber — who made the decision to fire Ruiz,
see supra
p. 246-47 — could not reasonably have believed that the disciplinary warnings were warranted.
Cf. Mulero-Rodriguez v. Ponte, Inc.,
Similarly, Ruiz attests that he was discharged due to his age, a belief based on his judgment that he had a good employment record. Even assuming his employment record passed muster, however, Ruiz proffered no evidence which would enable a rational jury to find that the Hotel’s employment action was not soundly founded on its determination that Ruiz possessed the least worthy work-performance-record among all competing Team Leaders.
Finally, Ruiz
alleged
that the Hotel conducted a systematic purge of older workers, but admits he has no such personal knowledge or evidence. It is axiomatic that more is required than mere conclusory allegations and unsupported conjecture.
See LeBlanc,
. Ruiz presented no competent evidence that the Hotel "riffed" him, or any other employee,
based on age.
There is no evidence of any comment by
anyone
associated with the Hotel, including Rivera and Greber, about Ruiz’s age or that age played
any part
in determining which employees would be let go. Moreover, the 1993 annual rating received from Rivera was the second highest Ruiz ever received. Nor did Ruiz address the undisputed evidence that all but two employees "riffed” by the Hotel were under forty,
see supra
note 6, which tends to suggest that the alleged systematic purge of employees was age-blind.
Cf. Hebert v. Mohawk Rubber Co.,
. We review the ruling on the motion to amend for “abuse of discretion.”
Resolution Trust Corp. v. Gold,
. Moreover, Vargas also received several commendations for work performance in the Housekeeping Department, the Hotel laundry, and as a driver and chauffeur, as well as performance ratings at least comparable to those received by Ruiz. Vargas earned the following annual perfor-manee ratings: 1987,4.4; 1988, 3.74; 1989,3.1; 1990, 4.0; 1991, 4.48; 1992, 4.3; 1993, 3.45; 1994, 3.59. See also supra note 4. In addition, Vargas had worked the day shift, which was regarded by Hotel management as more demanding than the night shift worked by Ruiz.
