The final rule setting a new salary threshold for overtime exemptions, now under review by the Office of Management and Budget (OMB), is still being attacked as overly aggressive by business groups.

The final rule reached OMB March 17. Since then, OMB has held 22 meetings with business groups seeking to tone down the rule. What most troubles these groups is the proposed doubling of the overtime salary exemption threshold from $23,660 a year to $50,440.

Even if, as reported by Politico Pro, the threshold is lowered to $47,000, these groups say the increase is still too much.

Another bone of contention is the proposed 60-day implementation window, which these groups say is way too short. They’re opting for as many as 180 days.
