Hello everyone.
I'm on ssdi and I would like to know how does social security count substantial gainful activity. Do they count the money I earned in a month, or was paid in a month?

As you may know this month is march, it has 5 weeks. I'm kind of cutting it close this month for earnings. I'm past my trial work period so $1000 is my limit.
Normally I earn $187 a week but this month I did some extra work at my job on 2 weekends. It's a union job so I earned all kinds of extra first shift premiums and stuff.

If assuming I earn my normal $187 the rest of month I calculate $1012 being paid to me as 5 checks for the month of march.

If social security only counts when the money was earned then they would not count the first day of the first week or the last day of the last week of march. This would put me back under the $1000 mark.

Please help I need to know if I should try and talk to my boss about letting me of early or or two days this week.

Thanks
