I would also call it JobsOrders, unless you come up with a better, succinct, description of the purpose of the table. For example, perhaps the description of the table is "This table stores information about how purchase orders are assigned or charged to different jobs" (you decide whether this accurately describes the purpose of the table or not!), you can use some of the words which I put in bold for the table name, which gives you one of the following alternatives: OrderAsignment, OrderCharge, OrderJobs.

In the above general description of the table I may have missed the point completely, but the point is to get some description of what the table does, and then either use some key words from that descrition (not words like "information" or "store" that apply to any table!), or alternately, if the table joins two other tables, use parts of the two table names for the join table.
