Gossip with a fellow power worker (6)

I believe the answer is:

gasman

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

'power worker' is the definition.
'gasman' can be an answer for 'worker' (gasman is a kind of worker). I am not certain of the 'power' bit.

'gossip with a fellow' is the wordplay.
'gossip' becomes 'gas' (I've seen this before).
'with' means one lot of letters go next to another.
'a fellow' becomes 'man' (fellow can mean a man).
'gas'+'man'='GASMAN'

Can you help me to learn more?

I've seen this clue in The Irish Independent.
