Do Forest City Ratner's part-time arena job numbers add up? If a maximum of 800 people work an event, it seems doubtful

We're going to hear about arena jobs at the Atlantic Yards District Service Cabinet meeting this morning, but I don't think Forest City Ratner's numbers add up.

(Updates: At the meeting, Forest City officials would not offer an estimate of how many hours part-time workers would work, which calls into question the total. I should acknowledge, however, that the arena needs to be manned 24/7, which means that there is at least a small crew working multiple shifts.)

They've estimated that some 2006 employees would be hired at the arena, 1901 of them part-time, 105 full-time.

And they say that works out to 1,240 FTE (full-time equivalent) positions.

How get 1,135 FTE positions?

Subtract the 105 full-time jobs from 1,240 and that means that the part-time jobs add up to 1,135 FTE positions. That's the equivalent of 1,135 people working 40 hours a week.

But Bruce Ratner has already said that the maximum number of workers at any one time is likely to be about 800, while smaller events could have only 500 workers.

If the arena was being used 365 days a year, the figure of 1,135 FTE jobs might make sense, because there might be more than 40 hours weekly of 800 people per shift.

But there are supposed to be 225 events per year. That means even less than a full-time year-round schedule, or an event for each of 250 work days.

800 workers per shift, on a daily basis?

So, would the 800 people at an event work more than eight hours? How many people would be working at the arena on non-event days?

Unless the events shifts are more than eight hours, and there are large number of people working on non-event days, the total of 1,135 FTE jobs seems unlikely, especially if you factor in the events which require fewer than 800 workers.

(Update:  As noted, I should acknowledge, however, that the arena needs to be manned 24/7, which means that there is at least a small crew working multiple shifts.)

Asking for clarification

I asked Forest City yesterday for clarification:

How would that add up to 1,135 FTE? Would the 800 people at an event work more than eight hours? (What's the typical shift?) Would there be large numbers of p/t workers at the arena on non-event days? Am I missing something?

Spokesman Joe DePlasco's response:

The number of hours per an event will of course vary. Each full time job is equal to approximately 1.7 part time jobs, as per the EIS.

That doesn't get us very far.
