And you have now set it up so that no user on your system has any private files; every file that they create in any directory on your system will be readable and writeable by every other user in the same group. Fortunately, I use the Korn shell instead of bash, so this wouldn't affect me.
Before you modified everybody'a .bashrc, did you at least warn them that they need to undo what you did or manually chmod every file that they create in any other directory?
Did you consider just asking users in this group to chmod files they create under this shared directory.
Did you consider writing a set-UID application that would allow users in that group to change the mode of any file under that directory (AND ONLY under that direcotry) to something any user in the group could use (and send a note to the offending file's creator and that person's supervisor) when it was needed?
At any company I've ever worked for, what you did would be a fireable offense. Please reconsider this action.

sticky(5) Standards, Environments, and Macros sticky(5)
NAME
sticky - mark files for special treatment
DESCRIPTION
The sticky bit (file mode bit 01000, see chmod(2)) is used to indicate special treatment of certain files and directories. A directory for
which the sticky bit is set restricts deletion of files it contains. A file in a sticky directory can only be removed or renamed by a user
who has write permission on the directory, and either owns the file, owns the directory, has write permission on the file, or is a privi-
leged user. Setting the sticky bit is useful for directories such as /tmp, which must be publicly writable but should deny users permission
to arbitrarily delete or rename the files of others.
If the sticky bit is set on a regular file and no execute bits are set, the system's page cache will not be used to hold the file's data.
This bit is normally set on swap files of diskless clients so that accesses to these files do not flush more valuable data from the sys-
tem's cache. Moreover, by default such files are treated as swap files, whose inode modification times may not necessarily be correctly
recorded on permanent storage.
Any user may create a sticky directory. See chmod for details about modifying file modes.
SEE ALSO
chmod(1), chmod(2), chown(2), mkdir(2), rename(2), unlink(2)
BUGS
The mkdir(2) function will not create a directory with the sticky bit set.
