Amend HB 768 by striking all below the enacting clause and
replacing it with the following:
      SECTION 1.  Section 451.002, Labor Code, is amended by
amending Subsection (c) to read as follows:
      (c)  The burden of proof in a proceeding under this section
is on the employee to establish that an action of the employee
protected under Section 451.001 was the substantial cause of the
employee's discharge from the position of employment.
      SECTION 2.  This Act takes effect September 1, 1997, and
applies only to a cause of action that accrues on or after the
effective date of this Act.  An action that accrues before the
effective date of this Act is governed by the law in effect when
the action accrued, and the former law is continued in effect for
that purpose.
      SECTION 3.  The importance of this legislation and the
crowded condition of the calendars in both houses create an
emergency and an imperative public necessity that the
constitutional rule requiring bills to be read on three several
days in each house be suspended, and this rule is hereby
suspended.
