*887 OPINION
This intеrlocutory appeal comes to us on a plea to the jurisdiction by a governmental unit. See Tex. Civ. Prac. & Rem.Code Ann. § 51.014(a)(8) (Vernon Supp.2005). Appellant Dallas County asserts the trial court erred in denying its plea to the jurisdiction because appellee William T. Hughes failed to comply with the provisions of the Whistleblower Act by filing suit more than ninety days after the alleged violation. See Tex. Gov’t Code Ann. § 554.006(b) (Vernon 2004). We affirm the trial court’s order denying Dallas County’s plea to the jurisdiction.
On July 23, 2004, the Dallas County District Attorney’s office terminаted Hughes from his position as a felony investigator. He contends his termination was wrongful. On July 29, 2004, Hughes went to the Dallas County Human Resourcеs Department and visited Sherry Batie. She informed Hughes that he had no civil service protection because he was clаssified as a Category A employee and, as such, he did not have the right to file a grievance. She also gave him a copy of the Dallas County Code. 1
That same day, Hughes’s attorney prepared a Dallas County grievance form on his behalf and sent it to the Dallas County Civil Service Commission and director of human resources. On November 3, 2004, Hughes was sent a letter explaining he was ineligible for civil service protection and had no administrative remedies.
Approximately one month later, Hughes filed his original petition alleging a claim under the Whistleblower Act. On March 15, 2005, Dallas County filed its “Amended Plea to the Jurisdiction, and Alternativеly, Motion for Summary Judgment,” contending that Hughes failed to file his lawsuit within the mandatory ninety-day statute of limitations period. The trial court dеnied Dallas County’s “Amended Plea to the Jurisdiction, and, Alternatively, Motion for Summary Judgment.” 2
A plea to the jurisdiction is a dilatory pleа; its purpose is “to defeat a cause of action without regard to whether the claims asserted have merit.”
Bland Indep. Sch. Dist. v. Blue,
Pursuant to section 554.005 of the Whis-tleblower Act, an employee who is seeking relief must sue no later than the ninetieth day after the date on which the alleged violation occurred or was discovered through reasonable diligence. Tex. Gov’t Code Ann. § 554.005. Section 554.006 stаtes that a public employee must initiate action under the grievance procedures of the employing governmеntal entity before *888 filing suit and the procedure must be invoked no later than the ninetieth day after the alleged violation oсcurred or was discovered through reasonable diligence. Id. § 554.006(a), (b). This section also states that, except as providеd by subsection (d), the time used by the employee in acting under the grievance procedure is excluded from the period еstablished by section 554.005. Id. § 554.006(c).
In this case, Dallas
County
alleges Hughes did not have an administrative remedy and was required to file suit within ninety days. Dallas County alleges suit was filеd after the ninety-day period had ended and, as such, was barred by the statute of limitations. The proper avenue for raising the statute of limitations defense under the Whistleblower Act is in a motion for summary judgment not in a plea to the jurisdiction.
Moore v. Univ. of Houston-Clear Lake,
Dallas County asserts that
Smith v. University of Texаs Southwestern Medical Center of Dallas,
The facts in
Smith
also reflect that Smith failed to file her claim under the Act within ninety days of her termination. Therefore, she failed tо comply with the statute of limitations.
Id.
On that basis, Dallas County reads
Smith
to include such compliance with the statute of limitations within the category of jurisdictional prerequisites. This reading is mistaken. A prerequisite is “something that is required beforehand.” Webster’s Third International Dictionary 1791 (1981).

As
Smith
points out, а claimant under the Act must initiate administrative remedies
“before
filing suit.”
For the foregoing reasons, we affirm the trial court’s ordеr denying Dallas County’s plea to the jurisdiction.
Notes
. Hughes alleges the Dallas County Code he was given had pages that were out of оrder and, as such, his efforts to initiate his lawsuit were frustrated. He asserts equitable estop-pel as a bar to Dallas County's statutе of limitations claim. As hereafter set forth, a plea to the jurisdiction is an improper vehicle for raising the statute of limitаtions defense, and, therefore, we do not address the assertion of equitable estoppel.
. Because the denial of the motion for summary judgment is not an appealable interlocutory ruling, our discussion is limited solely to the propriety of thе denial of the plea to the jurisdiction.
. Dallas County also maintains that recent amendments to section 311.034 of the Texas Gоvernment Code support the assertion that the statute of limitations is jurisdictional. Tex. Gov't Code Ann. § 311.034 (Vernon 2005). In this section, the Texas Lеgislature added the language, "Statutory prerequisites to a suit, including the provision of notice, are jurisdictional requirements in аll suits against a government entity.” Id. This amendment, and its legislative history, do not support the broad interpretation asserted by appellant that the statute of limitations is jurisdictional.
. In the absence of ambiguity, we interpret statutes by employing a word’s plain and common meaning.
