'ultimately this taxi's not one loved by unions' is the definition.
The definition suggests a singular noun which matches the answer.

'ultimately this taxi's' is the wordplay.
'ultimately' says to take the final letters.
'taxi' becomes 'cab' (synonyms).
The last letter of 'this' is 's'.
's'+'cab'='SCAB'
