What the meaning of the word "jump" and "filing" in this sentence?
In 2002, after a jump in people quitting and filing stress-related health claims, Best Buy launched an experiment: Employees would be allowed to work wherever and whenever they wanted, as long as they got their jobs done.
The following is my thought of these two words.
The jump means the step and the filing here is a ing-form of the verb file.
So the whole sentence is like this " in 2002, the company made the steps of reform after somebody leaving the firm and the satisfy the employees health requirements , the BestBuy has a new rule ............................................"
Could you give me the Synonyms of these two words?
jump
filing
If I was wrong, please correct my fault, thanks a lot.
