Journalists and technical staff at STV have walked out on strike in a dispute over pay, affecting coverage on the day of the Holyrood election count. Members of the National Union of Journalists (NUJ) said members, along with those at Bectu, which represents technical staff, are taking action over a pay freeze which unions said amounts to “a real-terms pay cut”.
