law.

   Under this court's precedent, only ultimate
employment decisions can qualify as adverse
employment actions. See Dollis v. Rubin,
77 F.3d 777, 781-82 (5th Cir. 1995). Threats,
reprimands, and warnings, because they do not
constitute ultimate decisions, do not suffice as
adverse employment actions. See Mattern v.
Eastman Kodak Co., 104 F.3d 702, 708 (5th
Cir.), cert. denied, 522 U.S. 932 (1997).

    Green’s only concrete allegation of
discrimination is the letter for counseling. This
plainly does not constitute an adverse
employment action under Dollis or Mattern.
Green’s unsubstantiated, conclusional
allegations of “harassment, intimidation, and
discriminatory actions” likewise do not
constitute ultimate employment decisions and
are not competent summary judgment
evidence. See Forsythe v. Barr, 19 F.3d 1527,
1533 (5th Cir. 1994).

    Green’s complaint that he was
constructively discharged would constitute an
ultimate employment decision, but this
allegation fails for lack of proof. A plaintiff
alleging constructive discharge must produce
facts tending to demonstrate working
conditions “so intolerable that a reasonable
employee would feel compelled to resign.”
See Barrow v. New Orleans S.S. Ass’n, 10
F.3d 292, 297 (5th Cir. 1994). Green offers us
only the letter of counseling and his
unsubstantiated assertions of discrimination
generally. The letter most certainly does not
