Like a free choice of ways to go to work (4)

I believe the answer is:

open

I'm a little stuck... Click here to teach me more about this clue!

'like' is the definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?

'a free choice of ways to go to work' is the wordplay.
'a free choice of ways' becomes 'en' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to go to' means one lot of letters go next to another.
'work' becomes 'op' (abbreviation for opus).
'en' after 'op' is 'OPEN'.

Can you help me to learn more?

(Other definitions for open that I've seen before include "Allowing access" , "yawning" , "Admitting customers" , "With which to offer hearty welcome" , "Candid - ready for business" .)
