No, you should set the group read, write, and execute permissions of the
directory to the permissions you want to allow for members of that group.

The set-gid bit controls the group that's assigned to new files created in
the directory. Normally they're assigned to the primary group of the
process that created the file, but if the set-gid bit is set then they
inherit the group of the directory.

If they want to share it with other members of their group, they set the
group permissions on the directory and files. If they want to share it
with everyone else on the system, they set the "other" permissions.
