In the latest twist in a lengthy and often bitter struggle, owner Govia Thameslink Rail took out double-page ads in Metro and the Evening Standard under headlines of "Let’s strike back", in which it warned of impending strikes before setting out conditions for employees and telling readers that the RMT "won’t listen to us but they may listen to you". Similar posters were put up on trains and at stations where it operates.
It also sent out a tweet inviting its 130,000 followers to tell the union how they felt, using #SouthernBackonTrack.
The response was instant, violent and predictable as passengers vented their fury against the company, accusing it of arrogance, incompetence, wasting money and trolling its own staff.

"Let's strike back". Nice try, @SouthernRailUK. @RMTunion have legit concerns & right to strike. Don't you dare try to use us to harass them

We support @RMTunion Southern guards taking strike action to protect everyone's safety on the railway. Today was another huge #SouthernFail. https://t.co/NmJ8hFaVdY

"Inflammatory", "tone deaf" and "ill-advised" were among the phrases comms pros used to describe the activity, as they told PRWeek Southern had sacrificed its right to comment and was reaping a whirlwind.
Within 24 hours – having garnered acres of negative coverage and nearly 20,000 disparaging tweets – the campaign was called off and Southern bosses sent an urgent email telling staff to destroy the posters.
