I have seen dates of 7/10 for SNL 7/24 for last day on pay roll.
If you are in Jon Summers group or now reporting to Jeremy Leg it will be later than that.
Percentages vary depending on group. I have see as low as 5% and as high as 50% (for levels 1 and 2)
General Managers less than level 5 are being cut at 40%. No idea what happens to level compression.
Level 5 and above is unknown.
Good luck to all.
