Layoffs at lab not fixed, pretend management (7,8)

I believe the answer is:

fantasy football

'pretend management' is the definition.
(hobby of pretending to manage football teams)

'layoffs at lab not fixed' is the wordplay.
'fixed' indicates anagramming the letters.
'layoffs'+'at'+'lab'+'not'='layoffsatlabnot'
'layoffsatlabnot' is an anagram of 'FANTASY FOOTBALL'.

(Another definition for fantasy football that I've seen is " management game".)
