If fines and workshops have failed to effect any sort of impact, other options include:

1) The University and/or the national office for the GLO banning the group in question from participating in any sort of new member recruitment for a full school year. This will weed out a lot of members due to graduation or sour grapes.

2) The university will require increased security at all Greek events, and any groups who do not comply will be placed on social probation for an extended period. Students who are in attendance at unapproved parties or who throw unapproved parties will receive some penalty in the form of community service, fines, or risk some form of academic suspension for causing the university a severe risk management issue.

3) The national GLO HQ should send a field consultant out to the chapter for a prolonged period of evaluation and leadership training.

4) The university can kick the chapter off-campus and/or the national GLO HQ can revoke the chapter charter, making these activities neither university nor nationally sanctioned.

ETA: What the chapter can do:

1) Monthly open forum where the chapter provides feedback and suggestions to the exec board without the exec board getting defensive and mouthing off.
2) Required member education monthly
3) Recognizing chapter members when they have gone above and beyond
4) Delegating leadership to chapter members, especially during these workshops
5) Asking for help from nationals, rather than fearing them, and being open and honest with nationals when a situation is brewing. They want to help-- they are not disapproving parents-- they are the management arm of your org.
6) Call people up to standards and be harsh--clean house. Numbers may drop, but so will the problems.
