AFL legend Kevin Bartlett was the first player to reach the rare 400-game milestone with only three other players having achieved this since.

The former Richmond player has since worked at SEN radio, but after 15 years and a change in ownership, tensions have raised, seeing Bartlett hand in his resignation.

It is believed that since Craig Hutchison became chief executive of SEN, Bartlett has not enjoyed his job. Before Hutchison was in charge Bartlett worked on the 9am-midday shift on SEN but has since been replaced by Gerard Whatley, forcing him to now work on the afternoon drive shift.

“I really enjoyed the old SEN and it’s fair to say I haven’t enjoyed the new SEN,’’ Bartlett told the Herald Sun.

Bartlett, now 72, resigned last Monday afternoon, giving his month's notice despite initially being expected to see out the remainder of the season.

“I’m going to do other things, I don’t know what I’m going to do, I’m just having a break,” Bartlett added.
