Players' union shows fairness (6)
I believe the answer is:
equity
This could be a double definition.
'players' union' is the first definition.
'equity' can be an answer for 'union' (I've seen this before). I am not certain of the 'players'' bit.
'fairness' is the second definition.
(synonyms)
'shows' is the link.
Can you help me to learn more?
(Other definitions for equity that I've seen before include "Fairness or impartiality" , "Fairness; shareholding" , "The ownership interest of shareholders in a company" , "Stake in business" , "One trade union" .)
