You have a parent process that each time you do a ps -ef and grep for your userid, you will see the same parent, but different children processes.
$ ps -ef|grep unixops
unixops 8075 8070 0 13:53:20 pts/11 0:00 grep unixops
unixops 8070 595 1 13:53:13 pts/11 0:00 -ksh
$ ps -ef|grep unixops
unixops 8077 8070 0 13:53:27 pts/11 0:00 grep unixops
unixops 8070 595 1 13:53:13 pts/11 0:00 -ksh
Note that each show pid 8070 (-ksh) but the "grep unixops" has different pids. After completing the requested work (searching for unixops), the child process died. This is normal.

ZGREP(1) General Commands Manual ZGREP(1)
NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the
standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep.
If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
